PVCs After Exercise: How Soon After Do They Count?
A cardiologist explains PVCs (premature ventricular contractions) that occur after exercise: how soon after do these matter; is there a cut-off point?
If someone has PVCs in the minute after stopping the exercise but not beyond a minute, does this count as “PVCs after exercise”?
“Yes, it does count as a PVC after exercise,” says cardiologist David N. Smith, MD, a board certified cardiologist with Premier Cardiovascular Care and Wellness in SC.
“But it does not necessarily imply significant risk without incessant or repeated runs, drop in blood pressure, passing out or having a significantly compromised heart.”
I’ve noticed that questions about PVCs occurring after exercise are fairly common in online health communities, so hence, my two questions here have some degree of overlap. So the next question then is:
What if someone has some PVCs 45 minutes after exercise?
Dr. Smith explains, “There should be no significant risk from PVCs alone. Irrespective of the time after exercise, PVCs don’t imply a risk unless there is some significant compromise to the person’s well-being (becoming lightheaded, dizzy or passing out), physical status or underlying heart function.”
If you’ve been noticing PVCs (premature ventricular contractions) soon after exercise as well as immediately after (slowing down on the treadmill, putting the barbell down, having a seat in the locker room, etc.), there is nothing to worry about if this is your only experience.
Note the signs for something to alert your doctor to:
1 Incessant runs
2 Dizziness and/or a previously diagnosed heart condition
3 Blacking out or feeling faint

How Often Do Heart Attacks Come After PVCs?
Do your premature ventricular contractions (PVCs) keep making you think that they mean a heart attack is coming?
There are some people for whom, no matter how many premature ventricular contractions they experience, and no matter what span of time these episodes have occurred (even years), they struggle with the same fear every single time a PVC occurs: “Will THIS be the one that causes a heart attack?”
For such individuals, which include those in their 20s, the millionth PVC is just as fear-inducing as the ones they had five years ago.
Each episode “resets” you to that baseline fear of a heart attack about to happen.
Here is good news: You do NOT have to live this way!
Is there any data on the percentage of heart attacks that are preceded by PVCs?
“Unfortunately there is no data to determine which percentage of heart attacks were preceded by PVCs,” says David N. Smith, MD, a board certified cardiologist with Premier Cardiovascular Care and Wellness in SC.
“This data will be limited by those who survived. Recall-bias, or the ability to remember what occurred during the event, also limits reporting.
“Nonetheless, PVCs are not considered a precursor to heart attack. Nor do PVCs reflect a recent heart attack or heart damage.”
Don’t Let PVCs and Fear of a Heart Attack Ruin Your Life
Dr. Smith says that premature ventricular contractions can occur in a normal heart but also a damaged heart (the damage being from something unrelated to PVCs).
“In and of themselves, the presence of PVC is not risky,” he says, and are not a crystal ball into whether or not a person is likely to suffer a heart attack.
“Many who have had heart attacks also get PVCs, and that may reflect a damaged heart,” says Dr. Smith.
“But the PVCs will not have been in the foretelling symptom, only a coincidental finding.”
If this isn’t clear, think of it this way: A person has a heart attack. It’s discovered there’s scar tissue (from past viral infection) on the cardiac muscle.
But this doesn’t mean that the scar tissue caused the heart attack.
However, the scar tissue reflects damaged cardiac tissue. It’s a coincidental finding.
“At some point, nearly everyone experiences PVCs. They are more of a reflection of the balance between the underlying adrenaline levels in the heart’s sensitivity.”

Can Insomnia Increase PVCs (Premature Ventricular Contractions)?
Are you losing sleep over the worry that insomnia can increase the frequency of premature ventricular contractions (PVCs)?
There can be a connection between premature ventricular contractions and insomnia because lack of sleep can cause a surge of adrenaline, says cardiologist David N. Smith, MD, a board certified cardiologist with Dynamic Health in Charlotte, NC.
This causes stress and agitation to the heart muscle.
“The heart then skips a beat felt as a palpitation but reflective of muscle twitching or premature contractions,” says Dr. Smith.
Insomnia often results from excessive worrying.
You lie down in bed for the night, and your mind becomes swamped with all of the stressors in your life — perhaps things that happened to you earlier in the day, or maybe all the tasks you must complete or start on the next day.
So you can’t fall asleep because you keep re-enacting the day’s earlier stressful events, including how you should have handled them, and/or, you’re envisioning the next day’s stressors and what the outcome might be.
This anxiety shakes up the body and incites a “fight or flee” hormonal environment.
Problem is, you can’t fight or flee while lying in bed. Instead, you’re trying to get to sleep.
The inability to fall asleep compounds the stress. Don’t be surprised, then, if you start feeling palpitations or PVCs.
Another consideration is this: Insomnia is frequently caused by stress, and so are PVCs.
They may occur together but not necessarily have a cause-and-effect relationship.
To help relieve insomnia and PVCs, don’t go to bed without first creating a “to-do” list for the next day, complete with any phone numbers and names of contacts whom you must do business with or interact with.
If you intend on visiting websites, have them already bookmarked.
Have your breakfast already prepared as much as possible (e.g., fruit washed and set out for the smoothie).
Have next-day’s clothes laid out and shopping list made, etc. Don’t eat close to bedtime; have your last fluid intake three hours before, if possible, so that you’re not awakened by nature’s calling.
If you have a clock radio, set it to a favorite station to turn off in 30 minutes.
Then get into bed and clear your mind. This will help reduce insomnia and premature ventricular contractions.

Zero Calcium Score & Normal Heart Structure but with PVCs?
What does it mean when you have premature ventricular contractions (PVC’s) but also a zero calcium score and normal heart structure?
Can the presence of the PVC’s still be indicative of something bad?
I asked this question to cardiologist David N. Smith, MD, a board certified cardiologist with Premier Cardiovascular Care and Wellness in SC.
Dr. Smith explains as follows, “The risk from PVC’s are related to risk of a heart rhythm abnormality that makes it difficult for blood flow and, in certain families, elevates the risk that the electrical system of the heart will become chaotic.”
In other words, the presence of PVC’s, whether you have a zero calcium score or not, becomes relevant if you already have a heart rhythm abnormality or are at risk for an arrhythmia.
This is not related to blockages in the coronary arteries, which is what the calcium score test looks for (hardened or calcified plaque deposits).
Dr. Smith continues, “This risk is different than the risk portended by a calcium score, which indicates risk of blocked arteries leading to heart attacks. In this light, the two are unrelated.
“The calcium score that is very high, however, may reflect ongoing atherosclerotic disease that secondarily lead to electrical system abnormalities manifested as PVC’s.”
Calcium Scoring
Calcium scoring is a diagnostic test performed using a CT scanner to evaluate the amount of calcium in the coronary arteries, which can indicate the presence of hard, stable plaque.
The procedure is quick, typically taking about 15 minutes.
During the test, you lie still on a table while the CT scanner captures detailed images of your heart’s arteries.
These images help assess the extent of calcium buildup, which can be a marker for coronary artery disease.
However, it’s important to note that calcium scoring only detects hard, stable plaque and does not reveal soft or unstable plaque, which can also contribute to cardiovascular risk.
This test is useful for assessing coronary heart disease risk and guiding further evaluation or treatment.
Ironically, some people, the idea of lying inside a scanner (especially one that emits radiation) that looks inside the heart’s arteries can be enough to induce premature ventricular contractions on the spot from anxiety alone.
You can ask the technician if they have any anxiety-relieving objects you can hold onto during the procedure.

Caffeine Causing PVCs: Why, & How Long It Takes
Find out why caffeine causes premature ventricular contractions (PVCs) and how long after eating or drinking this substance it takes to make your heart “skip” beats.
How long after eating (or drinking a caffeinated beverage) does it take a high-caffeine food to cause PVCs?
“Caffeine effect on PVCs or palpitations is almost instant,” says cardiologist David N. Smith, MD, a board certified cardiologist with Premier Cardiovascular Care and Wellness in SC.
“Likely a few minutes from being absorbed after consuming, but palpitations (the sensation of PVCs) may last for 15 minutes to hours afterwards.”
Anticipating premature ventricular contractions when you’re about to drink coffee can actually trigger them, if your anticipation involves enough anxiety, since anxiety can cause these “palpitations.”
Why does caffeine cause PVCs in some people? Mechanism?
Dr. Smith explains, “This is a reflection of the underlying individual’s sensitivity. The effect of caffeine has a same effect in all hearts, but not everyone would be as sensitive.
“It is thought that caffeine acts on the heart’s cells through something called a receptor.
“Once that receptor is agitated, changes happen within the heart muscle cell, including a change in the flow of calcium that promotes contraction or twitching in just a few cells, rather than the entire heart. This leads to the premature twitch or contraction.”

What Gives Hair Its Natural Smell?
Here’s the explanation for why hair has a NATURAL scent or fragrance, rather than what causes a BAD smell.
This isn’t a “Why does my hair smell bad?” article. It’s a “What gives hair its natural smell?” article.
I asked this question to Dr. Robert Dorin, DO, NYC-based hair care expert and restoration specialist.
The Answer to What Gives Hair Its Natural Scent
“The scent that a human can detect is a result of the natural oils that our sebaceous glands secrete on the scalp and hair shaft itself, along with natural surface bacteria and perspiration,” explains Dr. Dorin.
This is why, no matter what shampoo or conditioner you use (they come with a variety of fragrances), your hair will essentially smell the same.
Right after a shampoo, the fragrance of the product will dominate or superimpose upon your hair’s natural smell.
Sniff your hair after a shampoo, when it’s dry, and you’ll still be able to detect its natural smell, but with the juxtaposition of the product’s fragrance. Next day, this superimposition won’t be as strong.
At some point (unless you shampoo daily), your hair’s smell will be 100 percent from the natural oils (plus surface bacteria/perspiration).
Some people think that hair’s natural smell comes from products you put on it.
However, as the products’ fragrance wears off, your hair’s natural scent always returns to the same smell.
I began noticing this myself with my hair when I was about 11 years old. It always has the same scent after the shampooing wears off, though fresh after a shampoo, I can detect the scent (from the natural oils) mixed in with the shampoo/conditioner.
Intuitively I’ve always known that “it’s from the natural oils.”
The natural scent varies in strength. Some days it’s stronger than others, and I can often smell it when I’m just sitting still at my computer or lying in bed.
Your hair’s natural scent, from its oils, should NOT be bad.
Freepik
When your scalp is healthy, free of a skin disease or infection, your hair’s natural smell should actually be pleasant. I describe mine as sweet.
Like fingerprints, the natural scent of one’s hair from its oils is unique.
If we had the noses of dogs, we’d be able to differentiate among a million heads of hair!
What goes on under the skin in the scalp isn’t the same as with the armpits, as far as causes of odor, which is why your scalp—even when you haven’t washed your hair for a while and are perspiring—won’t smell like your underarms.
But have you ever sniffed other peoples’ hair?
Some women sniff their young children’s hair, enjoying the result.
I once read of a woman who had no choice but to inhale her young son’s hair as they huddled squeezed together in the basement during a tornado. She described it as “sweet.”
I’ve sniffed boyfriends’ hair, and it was always a nice scent—from the natural oils, not from shampoos and other products.
The natural scent of your hair should be a fragrance, not an odor.
If it’s an “odor,” then there’s either a fungal infection, dermatitis or an influx of environmental particulates (like smoke, cooking fumes) adhering to hair shafts, accumulating dirt, grime and dead skin cells—and causing natural bacteria to proliferate and feed off of this accumulation.
But if we’re talking just the natural oil production of the sebaceous glands (the oil is called sebum), this should actually be a GOOD smell.
Natural oils are essential for good scalp health. The oil production begins beneath the skin surface. Each hair follicle has a sebaceous gland attached to it.
The oil gets onto the hair shaft, making its way above the skin surface.
The sebum makes its way down hair shafts when you run your fingers through your hair, rub or scratch your scalp, and especially when you brush or comb your hair; the natural oils get “spread” down the shafts, which is why your hair emits a sweet natural scent even at the tips.

Soy Intolerance vs. Allergy, and IBS
There IS a difference between an soy intolerance and an actual allergy to this food, including how it relates to irritable bowel syndrome.
“It is important to differentiate soy allergy from soy intolerance,” explains Dr. Saad Habba, MD, an attending consultant physician at Overlook Medical Center in Summit, NJ.
“Soy allergy is a true immunological process that involves stimulation of immune response in the body and [the body] considers soy as basically a foreign object,” says Dr. Habba, a gastroenterologist.
“The body responds to this allergy like any other response and varies from simple symptoms such as abdominal bloating and discomfort, to rash and sometimes difficulty in breathing.
“The response is dependent upon the degree of reaction to soy, similar to any other allergen.
“Soy intolerance, on the other hand, does not involve a serious reaction to soy. In a sense, it would not cause any symptoms beyond abdominal bloating and discomfort.
“Unlike soy allergy, this never progresses to any complication beyond abdominal symptoms.”
Irritable Bowel Syndrome
Dr. Habba explains, “Soy intolerance is not very common and certainly is not as common as lactose intolerance, which can cause chronic diarrhea and abdominal discomfort in 10 percent of patients diagnosed with IBS.
“In general when one is treating symptoms of abdominal discomfort, bloating and diarrhea, one would first try to abstain from lactose-containing products before resorting to soy abstinence.
“If indeed soy intolerance is present, it would most likely be the cause for bloating, abdominal discomfort and diarrhea. It would not account for constipation or other symptoms of IBS.”
Thus, if you have IBS and are eating soy, chances are very high that your IBS symptoms are not being influenced by this, but by some other agent such as lactose or even mental stress.
Dr. Habba pioneered the concept of IBS being a wastebasket diagnosis and collection of different entities rather than a true single medical condition. He’s been presented and published in 26 national and international medical journals and symposia.

Does an IBS Attack Happen Suddenly or Slowly?
Here is information about the onset of an attack of irritable bowel syndrome.
“The onset of IBS symptoms is usually slow and ongoing for a prolonged period of time,” says Dr. Saad Habba, MD, an attending consultant physician (gastroenterologist) at Overlook Medical Center located in Summit, NJ.
Dr. Habba further explains, “Attacks do not come on acutely and do not behave as an ‘on and off’ switch. Accordingly, they may stay for days and sometimes weeks, particularly if the underlying precipitating factor is constantly introduced, such as lactose intolerance, sugar intolerance or stress.
“The association of stress and psychosomatic [physical symptoms worsened by mental stress] influences in IBS is well-documented — and may play an important role in the severity and length of symptoms.
“There is no set period as to when an episode usually occurs or disappears, as every person reacts differently to this condition.”
Mental Stress and IBS: Hand-in-Hand
IBS is now widely viewed as a gut-brain interaction disorder.
Research led by (Drossman et al, Gastroenterology, 2016) shows that people with IBS are more stress-responsive, and stressful life events are closely tied to symptom severity and persistence.
Stress and anxiety affect IBS in several ways.
Studies by Mayer et al (Nature Reviews Gastroenterology & Hepatology, 2015) explain that mental strain, pressure or worry alters gut motility, increases pain sensitivity and disrupts signaling between the brain and intestines.
This can can prolong symptom flares. Plus, daily stress or anxiety often precede symptom flare-ups in IBS.
Something Else to Consider
If you’ve never had any of these issues mentioned above, but then one day have a sudden onset of peculiar diarrhea that persists, don’t assume this is probably irritable bowel syndrome.
IBS has a great mimicker out there…
This happened to me, and even though a nurse thought it might possibly be a first-time attack of irritable bowel syndrome, it turned out to be a condition called microscopic colitis — which is frequently misdiagnosed as IBS due to a strong overlap of symptoms.

Strength Training for Prader-Willi Syndrome
Here’s why people with Prader-Willi syndrome should train with weights (strength training).
One of the classic features of the genetic condition of Prader-Willi syndrome is that of very poor muscle tone — the result of low muscle mass. Patients also have a very slow metabolism.
Muscle is the body’s most metabolically active tissue—it burns more calories just for sustenance than any other body tissue. This is something that every fitness expert knows.
Personal trainers, such as myself in the past, push the idea of performing compound strength training to boost resting metabolism.
A person with Prader-Willi syndrome will experience an increase in resting metabolic rate by building lean muscle tissue via compound strength training.
Curling dumbbells (biceps curls) is perhaps the most common weightlifting exercise.
Beginners are notorious for spending inordinate amounts of time curling.
However, it’s a very inefficient exercise for raising metabolic rate because it essentially works only one muscle group, the biceps.
This is a very small muscle group, and working it even very hard won’t do much to increase metabolism.
To get the greatest bang for the buck, a patient with Prader-Willi syndrome should perform compound strength training: more than one muscle group at once…and large muscle groups at that.
So instead of the biceps curl, the trainee would do a deadlift, bent-over dumbbell row, standing barbell row, lat pull-down and seated row.
Of these compound exercises, the deadlift is perhaps the best.
Shutterstock/Reshetnikov_art
Though this exercise is performed in strongman and powerlifting competitions, it’s one of the simplest movements to learn!
Don’t let the simplicity or “un-fanciness” of the deadlift fool you; this is one of the best exercises ANYBODY can do, including those with Prader-Willi syndrome.
Get Cleared by a Doctor First
Scoliosis (abnormal curvature of the spine) is another feature that often comes with Prader-Willi syndrome.
The patient should be cleared by a physician for strength training, particularly the deadlift.
Some strength training movements can be contraindicated by scoliosis, though not all PWS patients have this spinal problem.
People with Prader-Willi syndrome can gain muscle mass.
This was demonstrated in a study (J Pediatr 2003;142:73-8). Children and adolescents with PWS performed standing calve raises.
This is an isolation exercise (non-compound), but was chosen for the study because it’s super easy to perform and requires only a stair to do, rather than weightlifting equipment.
The report states: In persons with PWS, a well-defined and easy-to-accomplish training program improves local body composition and has generalized effects on physical activity and capacity, opening up a new therapeutic option to improve metabolic conditions.
If this is the conclusion of a study involving mere calve raises, imagine the metabolic effect that compound weight training (e.g., deadlift, overhead barbell press, bench press, lat pull-down) would have.
Working several muscle groups at once means that much more of an increase in lean muscle tissue—translating to an increase in resting metabolism.
This will have a positive effect on body weight management.
Other compound exercises to consider: flat and incline bench press, incline dumbbell press, seated chest press, leg press, kettlebell swing and weighted walking lunge.
There are many variations of the squat, but the Prader-Willi patient could benefit from whichever version he or she feels most comfortable with.
Some form of squatting (with a doctor’s clearance if the patient has scoliosis) should be included in the strength training program.
You may be thinking that a person with PWS should stick to “simpler” strength training such as using only machines, using tension bands and using very light dumbbells for various arm movements.
However, people with Prader-Willi syndrome perform in various sports for Special Olympics that require more coordination than a bench press, kettlebell swing, lat pull-down, leg press, squat and deadlift. They even do martial arts.
When Evan Matesavec was six years old, he achieved a black belt in taekwondo. At that time he was doing 25-30 pushups and has Prader-Willi syndrome.
Evan Matesavec in 2013
People with Prader-Willi Syndrome will benefit from “big” compound strength training movements.
The compound exercises I’ve mentioned require either standing in one spot, sitting or lying down (with the exception of the walking lunge).
Though my recommended strength training exercises are highly effective when performed for increasing healthy muscle mass, they are also very simple to do.

Colon Cancer Diarrhea vs. IBS Diarrhea: Is There a Difference?
A gastroenterologist discusses differences between colon cancer diarrhea and the diarrhea caused by IBS.
Do they look the same? How are they different?
You may have read that “constipation alternating with diarrhea” is a possible symptom of colon cancer.
The alternating feature here is a red flag (though benign conditions can also cause this).
But what about just plain diarrhea…without any constipation?
“Diarrhea is a rare symptom of colon cancer,” says Pankaj Vashi, MD, Lead National Medical Director, National Director, Gastroenterology/Nutrition/Metabolic Support, Cancer Centers Treatment of America.
“Diarrhea is usually related to travel, food allergy/intolerance or inflammation/infection in the bowel. Chronic diarrhea can be seen in IBS.
“Every patient with diarrhea should have a thorough evaluation including a detailed history and physical, stool, radiological and endoscopic studies before labeling it to be secondary to IBS.
“Diagnosis of IBS in a patient is usually made after excluding other treatable conditions.”
Don’t accept a diagnosis of irritable bowel syndrome until every other possible cause of your diarrhea has been ruled out, and that will require extensive testing.
Sudden-onset diarrhea, in the absence of having recently traveled or taken a new medication that can cause the side effect of diarrhea, can be alarming.
This happened to me. Where did my diarrhea suddenly come from? And it looked really weird, too.
Right away, the gastroenterologist’s nurse, as I was being prepped for a colonoscopy, mentioned that it could be IBS.
He also mentioned that it could be stress related, and he told me that his divorce had caused him to have diarrhea for three weeks.
But I was betting that his diarrhea didn’t look abnormal like mine did.
A doctor needs to look inside your colon, among other tests, before it’s determined that you have IBS.
Diarrhea, even weird looking, is a common symptom in the mass of population, though it CAN be caused by colon cancer. But it’s not a hallmark feature of colon cancer.
My diarrhea turned out to be caused by microscopic colitis (colon tissue samples are viewed under a microscope for diagnosis), a benign condition that does NOT increase the risk of colon cancer.
