Can PVCs Occur Often Enough to Cause Heart Damage?
“When many, many PVCs occur, up to several thousand in 24 hours, the lack of synchronized heartbeat can cause a temporary reduction in the heart’s pumping function,” explains cardiologist Dr. Pam Marcovitz, MD, an internal medicine cardiologist with Frankel Cardiovascular Center in MI.
“Fortunately, this is almost always reversible with catheter ablation.”
If you suspect that you’re having thousands of PVCs a day, then speak with your cardiologist about being set up with an at-home device called a Holter monitor.
You wear it around your torso and it records your heartbeats, including premature ventricular contractions, for 24 hours. The data will include how many PVCs you had in that period of time.
If you believe that your thousands of PVCs occur only some days out of the week, or even with less frequency, but still within any given month, then you can be set up with an event recorder for 30 days.
That all said, be assured that PVCs will not damage your heart tissue.
If you want to know what will damage your heart, it’s white sugar, high fructose corn syrup, trans fats and smoking, not to mention lack of exercise.

Can Stress Cause PVCs During Calmer Periods?
Can the stress of your life actually cause spontaneous PVCs during those periods when you’re in a more relaxed mood?
“PVCs may be caused by overall life stress, but are rarely caused by having a ‘bad day.’” says cardiologist Dr. Pam Marcovitz, MD, an internal medicine cardiologist with Frankel Cardiovascular Center in MI.
In other words, your bad hair day probably will not cause a premature ventricular contraction.
So if you occasionally have the so-called “one of those days,” this isn’t sufficient enough to trigger a run of PVCs.
However, if you have “one of those lives,” that is, an existence defined by ongoing stress and anxiety…then yes, this can bring on PVCs in a major way.
PVCs can result from acute anxiety, such as checking your phone for messages and seeing that one of the messages is from your doctor to tell you what your biopsy results are for that strange mole.
Your ponytail not turning out right is nothing compared to this.
Here come the premature ventricular contractions as you call the doctor back.
But where were they the evening prior when you were baking chocolate chip cookies with your young niece?
“PVCs may occur with too much caffeine, energy drinks or some medications that contain stimulants such as albuterol inhalers,” continues Dr. Marcovitz.
“They may also occur with alterations in blood electrolytes or abnormal magnesium levels. They may occur with anemia or sleep apnea.
“While PVCs may occur more frequently with life stress, there is rarely a direct relationship between the number of PVCs and having a bad day.”

How Can PVCs Cause Chest Pain?
Are you convinced that your premature ventricular contractions are causing you chest pain? You may want to rethink this idea.
“PVCs or premature ventricular contractions are ‘extra’ heartbeats coming from the bottom chambers of the heart,” explains Dr. Pam Marcovitz, MD, an internal medicine cardiologist with Frankel Cardiovascular Center in MI.
“They occur earlier than the normal heartbeat which comes from the top of the heart.
“The extra beat occurs in the pumping chamber and travels up to the top of the heart in backwards fashion from the normal heartbeat.
“Most of the time, PVCs are harmless, especially if they only last a second or two. PVCs are usually not associated with chest pain.”
If you’re feeling chest pain that seems to come right after one of your PVCs, this is most likely from anxiety over the PVCs in the first place.
Experiencing that sudden “ba-BOOM” from your heart may cause you to tense up, triggering an adrenaline surge — and some of that tension could be in your chest muscles.
Relax, premature ventricular contractions are not a harbinger of heart attacks.

Do PVCs Make Your Heart Skip a Beat or Is It an Illusion?
When you have PVCs, does your heart literally skip a beat, or does it only seem this way?
That “skipped” beat has been known to frighten many people, making them think that a heart attack is imminent or will occur in the near future.
So to find out what’s really going on with premature ventricular contractions, I asked cardiologist Dr. Pam Marcovitz, MD, an internal medicine cardiologist with Frankel Cardiovascular Center in MI. Her explanation applies to both women and men:
“Because the extra heartbeat happens earlier than expected, the heart’s normal beat senses the extra beat and pauses a few milliseconds before delivering its next beat,” explains Dr. Marcovitz.
“This pause is followed by a stronger heartbeat, and may be sensed as a skipped beat, a thump or a pounding sensation in the chest. Your doctor refers to this as a palpitation.”
Even a pause of just a few milliseconds can be perceived by the individual experiencing a premature ventricular contraction.
When you then feel that “thump!” that’s the stronger heartbeat, to compensate for that pause.

So with PVCs, there is no skipped heartbeat, only a very slightly delayed heartbeat. Premature ventricular contractions do not indicate an increased risk of a heart attack.
To lower your risk of heart attack, there are many things you can do, including:
Don’t let sodium (salt) consumption exceed 1,500 mg daily.
Drastically reduce consumption of processed foods.
Eliminate as much as possible processed carbohydrates.
Eat at least 25 g of fiber a day.
Sleep seven to eight hours a day.
Eat red grapes, berries, dates, almonds, walnuts, seeds, wild game and wild caught fish.
If you eat meat, limit it to grass-fed or wild game only.
Take the following supplements: green tea extract, turmeric and garlic.
Do both interval cardio training and strength training.
PVCs or the sensation of a skipped heartbeat are not a risk factor for heart disease.
So instead of stressing about that, pay more attention to how many hours a day that you spend in a chair.
Prolonged sitting is linked to a myriad of health ailments including cardiac related.

Pencil Stools Return to Normal: Can Still Be Colon Cancer?
If colon cancer is causing your stools to be pencil thin, this doesn’t mean that the stools cannot return to normal.
So if you’ve been noticing pencil thin stools and fearing colon cancer, do NOT feel reassured if this appearance at some point returns to what is normal for your bowel movements.
This returning back to normal does not rule out cancer of the colon.
The return back to normal-appearing bowel movements would simply be due to the tumor shifting position.
“Narrow stools can result from a very low rectal cancer or an anal cancer that is partially blocking the exit of bowel movement,” says gastroenterologist Sander R. Binderow, MD, FACS, FASCRS, with Atlanta Colon & Rectal Surgery.
He continues, “Stool size, however, is a very non-specific finding and does NOT confirm or refute the presence of a colon cancer.
“Most stool size and consistency is due to the environment (diet, amount of liquids, stress, etc.) and not due to colon disease.”
This is why narrow, pencil thin stools have numerous causes other than colon cancer.
Dr. Binderow explains, “Patients with diarrhea disorders, such as Crohn’s or ulcerative colitis, tend to have a thinner, looser stool.
“The inflamed colon cannot absorb water as well, nor gently distend to store stool. It comes out quicker and with less form.”
So what should you do if your BMs have become as narrow as a pencil?
There is a home screening test that you can take for colon cancer.
It does not diagnose this disease, but it uses the latest in DNA technology to detect cells that are abnormal.
The test is called Cologuard.
If the sample that you take from home is determined to contain abnormal cells, then a colonoscopy would be recommended.
Signs of Colon Cancer to Be on the Lookout For
Of course, you know that colon cancer can cause long, pencil-like bowel movements.
Or, with this disease, a bowel movement can come out resembling ribbons.
What would really increase the suspicion for colon cancer are additional signs such as blood in your stools, abdominal pain unrelated to BMs, and unexplained fatigue and weight loss.
Colorectal cancer can also cause a sensation that you still have BMs that need to come out, even though you just had a bowel movement.
Sometimes this is normal, and very soon after, you have another movement, and all is fine.
But colon cancer may create this sensation because the tumor itself is positioned in a way that makes a person feel as though they did not fully evacuate — even though they actually did.
- Blood in the stools — can be red or dark
- Old blood in the stools can appear black or like a tarry substance.
- Stools that are like ribbons or pencil-thin
- A feeling of incomplete voiding after a bowel movement
- Unexplained constipation or diarrhea that persists
- Alternation between constipation and diarrhea
- Odd changes in bowel habits
- Abdominal pain or gas
- A feeling of bloating or cramping in the abdomen
- Unexplained weight loss
- Unexplained fatigue
- Unexplained back pain
Dr. Binderow performs minimally invasive, robotic and laparoscopic surgery for Crohn’s disease, ulcerative colitis, colon cancer and other colorectal conditions. Adept at routine procedures, Dr. Binderow also sees patients with complex, atypical maladies.

Image Lets You Change Femur Length to See How It Affects Squat
For critics who think long femurs don’t matter in the back squat, play around with this virtual squat application and find out the truth!
Whether you want to believe it or not, femur length relative to torso length is a major determinant in a person’s ability to efficiently perform a back squat.
It’s puzzling that many muscle builders dismiss the long femurs excuse as poppycock, when the physics of this are actually quite easy to conceptualize.
I found an incredible site that has an interactive squat application, where you can alter the body’s femur length while maintaining the length of all the other body parts and overall height.
Before you visit the site (hyperlink coming), don’t blow it off as just an illustration and not the real thing.
It’s a very accurate depiction of what happens during the back squat relative to the athlete’s femur length as it relates to torso length and body height.
Believe me, as a personal trainer, I have poured over this fascinating phenomenon and size up the anthropometrics of all of my clients.
This interactive squat will be great for people who find it difficult to visualize the effect of varying femur lengths on a person’s squat. Conceptualizing this comes extremely easy to some people, but tricky to others.
Athletes who can draw the human body should find it a breeze to conceptualize the effect of lever lengths on the squat exercise.
I myself have been illustrating the human figure since early childhood as a hobby, so it’s very easy for me to “draw” out all the possibilities and animate them in my mind.
But you need not be an artist to understand “levers” and how they apply to movement…
Here is the link to the virtual squat. Have fun playing around with this; it is SO cool!
Just move the little button left or right to alter femur length, then drag on the man’s hip to make him squat! Drag slowly or else he’ll pop back up to standing.
The interactive tool will not allow you to get him into an unnatural squat position, such as ridiculously forward knees to compensate for the long femurs (try doing that and watch what happens!).
The interactive squat allows you to create crazy long femurs as well as crazy short thighs. This virtual tool will put to rest any of the rants by the critics.
Now, before you insist that the low and high end of the tool’s adjustment for femur length shows unrealistic proportions, keep in mind that even if that button goes just a LITTLE bit towards the long femur end (or short end), this makes a notable difference in squat mechanics.
Plus, there actually are people who have thighs so long (or so short), that this is a noticeable feature of their physique. Some people are self-conscious of their “long-ass femurs” or “stubby thighs.”
Though the guy with the short legs (including very short femurs to tibia ratio) and super long torso may be envied for his potential squatting ability, it’s important to know that no one body type can excel in all physical feats.
You’ll be quite hard-pressed to find any short legged, long-torso athletes in the Olympic sprint lineups.

Long Femurs vs. Short Shins when Trouble Squatting
Maybe it’s not your long femurs, but your short shins that make squatting troublesome.
There’s a lot of stuff out there about femur to torso ratio when discussing the back squat.
The “bad levers” of femurs longer than the torso for squatting (including for Olympic style lifting) get a lot of attention in training forums, but something gets very much overlooked: femur to shin ratio.
As a former certified personal trainer, I’m always looking for this trait in people, but it’s quite uncommon.
See the diagram below. Though crude, it clearly shows the disadvantage of having a short shin to longer femur ratio.
What happens when they parallel squat?
The figure with the short shin can’t get his feet under his hip bones. There just isn’t enough shin length to act as a “pedestal” for his squatting body.
Because his shins are so short, his feet are displaced far forward of his hips, requiring him to have an excessive forward lean — even though his femurs may be the same length as his torso or even shorter.
The second figure has no problem sitting down into a squat while his back stays closer to upright than folded over.
Because there is more length in his shins, his feet are more under his hips.
This means he doesn’t have to lean that far forward to get his shoulders over his feet. Think of his super long shins as supportive pedestals to just sit on.
The long femur in relation to short shin is a proportion that is not determined by overall body height.
Thus, a very short person can have femurs several inches longer than their tibias, and a very tall individual can have shins four inches longer than their femurs.
Conversely, a 5’4” athlete can also have short stubby femurs, such that most of the leg is tibia, and a 6’7” athlete can be mostly femur.
- Overall body height is not a factor in the femur-to-shin ratio.
- Torso length will vary and is not related to femur-to-shin ratio.
So if your femurs aren’t longer than your torso yet you fall backwards as your squat nears parallel, it could be due to not having long enough “pedestals” to support your body.
Short shins prevent the feet from getting far enough under the hips — the feet are displaced too far forward. So to get the shoulders over the feet, you may need to practically fold in half.
So how does someone with these levers do a back squat without folding in half?
Widen the stance (this will take getting used to and increasing the hip flexibility) until you no longer must double over.

The knees must track over the feet when squatting with a wide stance.
Pointing the feet outward to 20-30 degrees will make the squat even more doable for someone whose shins are disproportionately short for the rest of their body.

High Intensity Interval Training for Overweight People
There is no medical reason why an overweight person cannot or should not do high intensity interval training (HIIT).
However, the modality of the exercise would certainly come into play for an extra heavy body.
- High intensity interval training doesn’t have to be speedy or fast in order to be effective.
- The ability to run is not required.
Many people associate high intensity interval training with sprinting and jumping.
Though fitter, swifter people who want to do HIIT will be drawn to sprinting and jumping as the modes, this does not mean that slow movement can’t be effective for a HIIT workout.
Effort Is the Key
High intensity interval training is about effort, not speed.
An effective HIIT session for a very overweight man or woman could be their fastest walk — absolute fastest — up a slight hill in a road.
After about 30 seconds, they can then walk slowly and comfortably in the opposite direction back to where they began, catching their breath all the way.
After a minute or two, they can then power walk — truly as quickly as possible — once again down the road.
Though this isn’t a speedy workout, it’ll be quite effective for a very heavy person whose body is only used to slow movement.
At an all-out effort of charging up that slight hill, this will be enough to really exhaust the overweight body, even though running or high speeds are not involved.
Staircase charging is another option. For a plus size individual, briskly marching up steps can be grueling — and very effective at burning fat.
Other than Walking
Walking as fast as possible is but one of many modes for HIIT.
Other options for an obese man or woman include quickly stepping up and down the first stair of a staircase, and cardio equipment such as an elliptical machine and stationary bike.
This means pedaling for about half a minute at your maximal speed, relative to the pedal resistance.
Following that would be an easy pedal for one or two minutes.
Then after your recovery interval, you repeat the sprint pedaling.
The bottom line is that the settings for that 30 second segment are such that 30 seconds leave you nearly breathless.
You can also try HIIT using varied work intervals if they work better for you, such as 15 or 20 seconds for the exertional phase, or a little longer than 30 seconds for the hard effort.

Glucerna Ingredients Include Soy & Artificial Sweeteners
Is Glucerna really healthy for people with diabetes, since these products are so highly processed?
The Glucerna trademarked slogan is “Smart nutrition for people with diabetes.” Perhaps you’ve seen TV commercials for Glucerna, and if diabetic, have concluded that these products are super healthy for the human body.
Below are the ingredients for Glucerna’s “snack shake,” chocolate — and these ingredients are similar to those of Glucerna’s chocolate bars.
Water, corn maltodextrin, fructose, milk protein concentrate, glycerine, high oleic safflower oil, cocoa powder (processed with alkali), less than 1% of: sodium caseinate, canola oil, soy protein isolate, fructooligosaccharides, soy fiber, cellulose gel, natural and artificial flavors, sodium chloride, magnesium phosphate, potassium citrate, calcium phosphate, soy lecithin, cellulose gum, choline chloride, ascorbic acid, carrageenan, acesulfame potassium, potassium chloride, gellan gum, sucralose, and the remaining ingredients are vitamins and minerals, though ascorbic acid is vitamin C.
A health conscious person, whether diabetic or not, will notice several ingredients in Glucerna’s products.
These would be the soy, canola oil, artificial flavors, sucralose (an artificial sweetener), acesulfame potassium (another artificial sweetener) and fructooligosaccharides (yet another artificial sweetener).
Canola oil contains hexane and trans fats. Though this oil has some redeeming features, it makes sense that a health conscious person would want to avoid ingesting hexane and trans fats.
And soy — the unfermented kind — has been linked to some health issues, and its effect on the body is debatable as far as beneficial vs. potentially harmful. Plus, some people are allergic to it.
Processed soy in a bottle is not the same as tempeh or miso soup.
Need I say anything about artificial sweeteners? Well, one thing’s for sure: Scientists are divided on the safety and risks of artificial sweeteners, even though animal studies are quite compelling.
A diabetic may figure that controlled blood sugar trumps any possible harm linked to canola oil, soy or artificial sweeteners.
Final Verdict About Glucerna for Diabetes
The carbohydrates in Glucerna’s products are designed to be more slowly absorbed into the bloodstream, something that would appeal to diabetics for blood sugar management.
As far as strictly blood sugar absorption, a serving of Glucerna chocolate products are much better for a diabetic’s glucose metabolism than would be, say, a chunky piece of Betty Crocker devil’s food cake.
Both items are highly processed, but Glucerna is more preferable when you look at the overall picture.
So when you compare it to Duncan Hines, Betty Crocker or Walmart’s chocolate baked goods, Glucerna is the best option, relatively speaking.
The Glucerna “snack shake” is gluten- and lactose-free, and an 8 ounce can offers: 140 calories, 5 grams fat, 230 mg sodium, 19 grams carbohydrates, 3 grams fiber and 7 grams protein.

Childless Adults Qualified to Give Parenting Advice
After you read this, you’ll be convinced that sometimes, childless people are heavily qualified to dole out parenting advice!
But first, are you one who believes that people who’ve never had children are out of line for giving parenting advice?
According to this line of reasoning, any person who’s raised kids is qualified to give parenting advice. But come on, we know this is so far from the truth. Would YOU take parenting advice from Britney Spears, Kate Gosselin, Mama June or Bobby Brown?
Think of one of the most selfish, narcissistic, impatient and uncaring adults you know. Does that person have kids? What kind of parenting advice do you think they’re capable of giving?
Good parenting advice will come from loving, clever, creative, patient, affectionate and rational people.
And bad parenting advice will come from bitter, emotionally distant, self-centered individuals, especially those with anger management problems.
It doesn’t make any difference if this latter group has raised 10 children. This quantity simply means they’ve imposed their crippling traits on 10 kids, not zero.
“A person does not have to have walked in another person’s shoes in order to give them advice,” says Stacy Kaiser, a southern California-based licensed psychotherapist and relationship expert with a special interest in the topic of bullying.
“You do not have to have been an alcoholic to have suggestions for someone who drinks too much,” continues Kaiser with this analogy. “Similarly, you do not need to have a child to offer up parenting suggestions.”
Or as the saying goes, One need not be wearing your shoes to see that your shoelaces are untied.
It’s important to note that Kaiser says that “having lived the experience of being a parent, one does pick up tools and ideas that they may not have had,” in the absence of parenthood.
You may know of someone who has five kids and want parenting advice from them simply based on this.
- What if you learned that this adult was prone to temper outbursts and had little patience?
- What if you learned this individual never read to her children when they were very young?
- Never tucked them in bed?
- And when her daughter goofed up during a piano recital, the mom shamed her afterwards?
- Would you still want this woman’s parenting advice?
My brother sought parenting advice, prior to having children, from a psychiatrist who had no children.
My brother’s three kids are among the most self-confident, emotionally stable human beings I’ve ever met. They are what you’d say are “going somewhere big in life.”
Still think people without kids have no business telling others how to raise theirs?
Whom would you want as your young child’s nanny?
A 45-year-old narcissistic, impatient, arrogant, high-strung woman who’s quick to criticize over every little thing—but has raised four children?
Or a same-age woman who’s never had kids—but, is very tender, calm, patient, warm and cozy to be around, is quick to praise and is fun-loving and kind-hearted? The answer is a no-brainer.
Sometimes, a childless person is in a prime position to give parenting advice simply because they are skilled at creative problem solving. Sometimes they simply have common sense.
Sometimes it’s because their parents made enormous mistakes. An example might be a man named “Rob” giving advice to a buddy, “Steve,” who has a 13-year-old son on how to handle the son’s complaints that he’s getting bullied at school.
Maybe Rob was brow-beat by his father for being a “wimp” at school, and this made him even more vulnerable to the bullies, feeling more powerless.
This poor guy, as an adult, may very well have stellar advice for Steve that could lead to empowering the 13-year-old.
Isn’t it funny that the criticism of, “What do YOU know? You don’t have kids!” never applies to when the childless person gives advice that the parent actually agrees with? Now that’s something to really reflect upon!
An adult is either a bad person or a good person. Having kids usually will not alter that status.
With so many parents out there “screwing up” their children, how can anyone denounce the concept of childless people giving parenting advice?
