monicaq,
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
holterHolter monitor (24h) 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-testosterone mc, you need to establish that the
palpitationsHeart 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?"
See Q2.
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.
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!
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.

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 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!
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!
I never noticed anything unusual during exercise.

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,

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?

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.
I get them everytime I run. It used to frighten me. Now it's no more a bother than a hiccup.

That explains some of it to me. How long have you been dealing with this? I've only had them a couple of months and I'm still not comfortable with them.
Gordie
I would totally agree on the effect of adrenelin...in some instances before a b-ball game, the PVC's would kick in just as I was arriving the gym in anticipation of the game. While very frustrating to say the least, it is also very intriguing to me as I find myself constantly looking for certain triggers, etc.
I guess it is reassuring in a funny way that other athletic/active people experience the same thing. There are a number of different forms and chat rooms on this subject but there wasn't a lot about exercise-induced PVC's so this dicussion is much appreciated. I think this area merits more research...I would certainly be a willing participant..or guinea pig in any type of research!

I am new to the heart forum. I am a 36 year old woman, and many of your posts might as well have been written by me. I've been dealing with what I now know are PVCs for about 15 years.I have had months, maybe even a year, go by where I don't feel any. Then, they will seem to come out of the blue and last for weeks. Most recently, after about 9 months with no symptoms, I had what might be the worst episode yet. But I also (finally!) had an ECG which indicates mild MVP.
Since this last ongoing episode, I have been afraid to run or exercise in any form. Last summer I was up to 10 miles with my running - now I don't even like to go up a long flight of stairs. Sometimes I see a link between PVCs and exercise, other times I do not. I strongly agree with the people who say its much easier said than done to "keep going" in the presence of multiple and frequent PVCs - anyone who has experienced them knows they are impossible to ignore. I hope to start exercising soon - I guess I'm waiting for my follow-up doctor's appointment for reassurance that I won't be dropping dead. I have to admit I am intrigued by the hospital gym idea!!
Thank you to all for sharing your experiences - I really can't believe how similar they are to what I have been going through.
Theses stink! Like a lot of you, I quit my workout as soon as I get one. I pray someday there will be a cure for us. Take care everybody.
I am a 24 yr old feamle, non-smoker, in good physical condition. After finding single pvc's on an event monitor, my cardiologist ordered a Holter, which found a run of 3 consecutive pvc's. She termed this paroxysmal ventricular tachycardia -- Clearly, I am horrified. A cardiac MRI showed no structural abnormalities, and blood work indicated no thyroid dysfunction and only mildly low potassium levels(3.3).
My question, then, is how dangerous is the vt? I live in a constant state of panic, worried that I could drop dead at any minute. My Dr says the 3 slow,extra beats are likeley no cause for concern, but I'm petrfied and seek others' opinions.
THNAKS, AND ALL HELP IS APPRECIATED!!
