Thanks for the post.
Q1:"Is there anything that I have described that raises questions or causes concern with you?"
A diagnosis is necessary so that you can feel good about exercising again. If a holter monitor is ineffectual, then have an event monitor or Cardionet placed.
Q2:"If I were to take up running again and this continues to happen, what advice do you have for me if this recurs? Do I just keep running and ignore the 6-12/minute PVCs that I'm getting when my heart rate is up around 150-160? "
First, you need to establish that the palpitations are indeed PVCs. It is unusual for a person who doesn't feel PVCs at rest to then be troubled with them during exercise. If indeed they are PVCs, and you have an otherwise structurally normal heart, then it is generally thought that the presence of the PVCs is not associated with an adverse prognosis.
Q3:"there any more danger with PVCs like this at a heart rate like this?"
Q4:"Why would I be getting these in this pattern only during exercise?"
I don't know. Some people do get stress-induced PVCs, but it is less common. First, a diagnosis of PVCs needs to be established.
Q5:"And finally, if the PVCs can come on at a rate of one every other beat or two or three, etc., what is it, physiologically, that keeps them from deteriorating to VT or V-fib?"
A PVC is caused by an automatic focus in the ventricles that "fires" every now and again when the conditions are right. VT requires a circuit, which is most commonly produced in humans by scar formation from heart attacks. VF is different again altogether. VF requires varying refractory periods or conduction times in the heart to setup local wave forms whose "sum" does not add up to a contraction. Varying refractory periods or conduction times requires an abnormality of the heart muscle cells, like from a genetic disorder or from a heart attack.
Hope that helps.
PVC's can be very upsetting and also debilitating at times. Light feeling pvc's aren't very bad, but the more forceful ones that make you lightheaded, dizzy, fainty, etc., are the kind that 'take you down'. That's the kind I have. I walked for only 0.2 miles last evening and then pvc's hit so often and forceful I could hardly make it back to the house.
Dr's always tell me... "we know they are uncomfortable but they are not life threatening". Sorry, but they are not the ones having them and they don't know how uncomfortable they are.
If you can continue to run while pvc's are happening, I say keep on running. I hope you never have them as I do.
I suffered from the exact same thing you describe. I thought I made them go away by agressively hydrating, but they would still happen with exercise. So much so that I felt like I had very few nl beats, with frequent feelings of fluttering. A cardiologist running partner and I were actually subjects of an office pool to see who had the most ectopic beats during a 15 min treadmill run. I won, primarily because I was given extra points for bigeminy and trigeminy, as well as couplets and triplets.
I have been lucky to have been able to make dietary changes which have reliably completely eliminated them. I have eliminated all products with sig amts of glutimate, including soy milk, energy bars, prepared frozen meals to list a few. Glutimate is an amino acid used to increase the protein content of foods and as a flavor enhancer. People recognise one form, MSG, but it also the main ingredient in: yeast extract, calcium or sodiun caseinate, soy or milk protein isolate, hydrolyzed vegetable protein, natural flavors and more.
Interestingly, if you search and read about MSG, the studies sited mention that women seem to be more sensitive to the arrythmic effects of glutimate, particularly with exercise.
Good luck! and keep running!
im 28 probably 40-50 pounds overweight and a smoker and have been having pvc for atleast 6 years they are getting worse and leave me out of breath and very light headed i get them every single day but i know they are aggravated by caffeine and im addicted to coke soda but i do notice when i stop drinking the soda they become less much less but i have frequent chest pains that come and go also weakness on my left side but i dont know what to do myself its been about 4 years since i have checked my heart i have family history of heart disease and im paralysed with fear sometimes i think im making myself sick anyone with advice can email me at ***@**** thanks so much
I get more pvc's with exercise. I use to run 2 miles three to four times a week but I stopped completely a year ago because I started getting the pvc's. I try to walk twenty to thirty minutes two or three times a week but it's hard because the pvc's scare me. They really have taken over my life. If anyone has a good workout plan to ease into I'd love to hear about it. ***@**** Thanks
i have exercise induced PVC's as well - i have had them for years but in the past three years they have increased during exercise. i also have them very occasionally when i am not exercising. i admit i have stopped exercising as much, simply because of the worry but in the past month i have cut out caffeine completely, which has really helped.
I don't understand why the doctor would find it unusual to have more PVCs with exercise, given the established link between PVCs and other stimulants in some people. Adrenaline is a stimulant, right?
That said, I get more PVCs with an unhappy stomach than anything else. That is, if I've had a heavy meal the night before, with onions or alcohol, I may get 2 or 3 PVCs during exercise the next day. Most of the time I have no PVCs during exercise, and my heart rate gets up to 164.
you said VT was caused by scar tissue from a heart attack. could it be caused from scar tissue from an ablation for PSVT and AVNRT. this may be a stupid question but i always wondered if the scarring from the ablation has something to do with my pvc's. its my worse fear that it will turn into vt or even vf.
have PVC's sometimes several daily, some wake me up at night with stomach upset/gas like they are doing as I write this. sometimes I go days without a one. My Cardiologist too told me to keep running during exercise when I feel them. he said "Just run through them." Well, like most have said here, it is easier said than done. It messes with my head too even with reassurance from a Cardio. If I have one, I can usually ignore it and keep running, but if I have a couple 2-3 in a row or in a minute, I usually stop and quit. And it really stinks, because we are all trying to get or stay heart healthy by running, jogging, walking. I'm sure many can relate to this: You are really feeling great, going to the gym, had a good day, and the first few minutes on the treadmill are awesome. You have that euphoric feeling of accomplishment, you are enjoying some stress relief and you have now been running for 5-8 minutes striding it out. Bam! A PVC. OK, no big deal you think, keep going. Another PVC. Why me I say. Why can't I be like all these people next to me jogging and working up a sweat. All that enjoyment I was feeling is gone and usually I'll stop not wanting anymore PVC's. I love the days when I exercise and have none, about 50% of time. When I'm rested, well,well hydrated, not had alcohol night before, and had some carbs before running, have had my best success w/o the PVC's.
I've had mixed information on PVC's after working out. I seem to have afew extra, Maybe 6-7 per minute, for 5- 10 minutes.
I've read where PVC's after a workout can be significant. Do they mean 6-7 per minute or do they mean bigeminy PVC's.
TOO FUNNY!! Now that's the mental state I need to get to...let's have a bet to see who can get the most ectopic beats during a run! I will have truly beaten these things if I can get to that point! Thanks for the story. It's a great one. Does this still happen to you when you exercise? How often? I think I need to go out running and have these things hit me like they've done in the past, and just press on and finish a four-mile run, even as they keep coming. I can so relate to as1723's post, because that is typically what I do--I quit once I start getting them. And now, I don't even try at all because I'm afraid of them...and these aren't the occasional ones. I can live with those. It's the repeated, every-so-many- beats ones that I can't run through.
I know EXACTLY how you feel when you start a run and want to stop when they start rolling. I remember stopping to feel my pulse, in some sort of denial that they weren't really happening. One thing that helped me run through them before I figured it all out, was to run on the treadmill at my gym. Normally, I only run on a treadmill as a last resort in inclimate weather, but I found some sort of sick comfort knowing that if I dropped dead while on the treadmill, there was a reasonable chance that someone would revive me. Obviously, I never dropped dead, but it helped me run through some disturbing palps, which gave me confidence.
I am so grateful to have found a dietary solution. My cardiologist friend thinks I'm full of hooey, but he's still palping, and I'm not. Every now and again, I throw caution to the wind and eat things that I have blackballed, and I get return of my palps, not nearly as bad, for about 48 hours, only if I exercise.
I look forward to reading a post from you letting us know you've conquered them!
So, you actually FEEL the skipped beat despite rapid beats during exercise?!?!
I never noticed anything unusual during exercise.
I have noticed I have more skipped beats with exercise as well...it makes me not want to do anything but sit still. I hate feeling that way. I know exercise is good for me but I am afraid to do it. Also I notice more skips when I have a full stomach, and when I need to have a bowel movement. Why would this be so? Does anyone else experience more skips at these times? heartdancer
WOW!! CONGRATULATIONS on your new lease on life! What a great idea. Have fun at the gym!
Very happy for you that dietary changes have made a difference for you. It sort of gives one a sense of control over the whole thing. I think we are all very different and sensitive/not sensitive to various things.
I am not at all suprised to hear that slimfast products are loaded with glutimate. Perhaps you, like I was, are having unpleasant effects from it.
There is a website called www.naturodoc.com. Very informative site for all sorts of things. If you go to the site index, page 2, under the category of nutritional concepts, you will find a page about glutimate (MSG). The list of ingredients to avoid is the same as all the others I have found. I avoid the ones under "always contain MSG" and don't worry about the others. I spend a lot more time in the store and in the kitchen than I used to, but WELL worth it.
Hope the same for you!
HEY EVERYBODY.IM 31 AND HAVE FREQUENT PVC'S.ANYWHERE FROM 10 A DAY TO 1000 ADAY.I GET BIGEMINY,TRIGEMINY ETC.

your story sounds very much like mine although I'm 40 and I never was a champion athlete; I cycle and weight train. I'm now at the stage where I'm able to exercise again without the fear of palps/pvcs/panic. I have been training at approx 65% of the intensity that I had prior to my problems. I too have eliminated caffeine as well as alcohol, art.sweeteners, and are taking some supplements. I feel much better than in the past and hopefully I can push a bit harder at some point. I'm holding back fearing an episode and setback in my progress. Are you able to run at the intensity that you once did?
GLAD TO READ THE COMMENTS,LIKE I SAID I EXERCISE 3 DAYS A WK.AT THE HOSPITAL GYM,BUT I STILL AM BOTHERED GREATLY BY PVC'S,AND PANIC ATTACKS.TODAY IS A STRUGGLE TO JUST STAND ,BECAUSE I FEEL PVC'S EVERY FEW BEATS.AND IT STILL SCARES ME TO DEATH.BUT TOMMOROWS MY GYM DAY,AND I LOOK FOWARD TO IT.ITS A GREAT CHANCE TO SQUEEZE A LITTLE EXTRA REASSURANCE OUT OF THE Cardiac rehab nurse.I LOOK FOR ALL THE MEDICAL REASSURACE I CAN GET.AND I JUST KEEP CHUGGIN' ALONG.
just chiming in with additional, though similar, comments. i have not visited this site in awhile, and it's always reassuring to read about folks suffering from similar maladies, as well as the creative approaches to dealing with them.
as for me, i was a state champion miler in high school, ran competitively in college, and, at 25, developed frequent exercise-induced palps. in the years that followed, i quit running (and exercising, in general), began having panic attacks, and developed a constant, nagging fear that i was in imminent peril. not good times.
now, at 32, i'm finally able to run again, although i'm still troubled by the palpitations (even though i've been given a fairly clean bill of health). my suggestions, like most here, is to get checked out, and then forge ahead. and stay well-hydrated. and cut out caffeine. and, to coin a phrase, just do it. take care,
Has anyone ever explained to you why PVC's occur with HR going up and cooling down? I'm new with PVC's and still trying to find answers.
When I try to even walk, I start having pvc's. No, not just pvc's, but very debilitating pvc's that take me to my knees. Makes me feel like I am dying. Shortness of breath, pressure in chest, etc.. I get so fed up with this going on all the time. I can't even go anywhere by myself anymore for fear of needing help and most people do not have a clue as to what is happening. I am not blaming them, it's just that it's so frustrating for all concerned.
Finally, some good discussion specifically about exercised-induced PVC's. For myself, I like to run and play basketball. My own experience has been that the PVC's only occur either when the heart rate is on the way up or during the cool down period. (During the peak or height of the exercise - be it running or at a during a B-ball game, I rarely get them. Having said this, there have been times when I don't get them at all during exercise which really leaves you confused.
Like most of you, I have gone through the full gambit of tests and have been told to keep to my normal exercise routine.
I've experimented with some supplements and reducing carbs - I saw some improvment, particularly with the carbs, but didn't stick to it long enough to really know the true effect...must try it again.
As many of you have already said, we must find a way to fight through this...for me...I need to start running half marathons again which I really enjoy...can't let this annoyance get in the way.
PVCs (and PACs) will have a tendency to increase with an increase in adrenaline (if they originate from foci). Thus, you may experience an increase when first starting to exercise and just after finishing (since the adrenaline levels will remain high for some minutes). As I understand it, for focally-induced PACs/PVCs, the foci respond to the adrenaline stimulation and increase their twittering both in frequency and in amplitude. Their abberent signalling is thus increased and with it, the likelihood of some of that pulsing ion action reaching the pacemaker circuitry (eg, AV node)...and when that happens, boing, a premature beat followed by the engorged makeup beat.
I get them everytime I run. It used to frighten me. Now it's no more a bother than a hiccup.
