No PVCs During Exercise---Why?? - Heart Disorders Message Board

I mentioned this in another thread but thought one with its own subject might catch peoples' attention and create a little discussion.

I have pretty constant PVCs with the usual tests showing no heart problems and with the usual admonition to "not worry about it". (I am 5 weeks post angioplasty/stent, but was not previously bothered.)

I have not detected any particular time of day when these things are absent, and they seem more prevalent after my evening meal. But I do notice that they are completely absent during exercise (treadmill with pulse monitor). From a resting rate of 72 bpm with numerous PVCs/minute, I get up to 100 bpm or beyond and do not notice anything (I stop the treadmill and take the pulse). Cool down, and things are regular (no PVCs) until I am back down to resting rate.

Why is that??? Has anyone else noticed the same thing?

Thanks for any comments.

Same here - I can have many hours of PVCs on a daily basis, but rarely get any during exercise. I'm like you - mine are usually the worst after my evening meal, and just when I'm trying to relax. I noticed that if I get very tired during the day, the PVCs are usually worse that night. But for some reason, exercise usually straightens out my PVCs - at least temporarily.

Another perplexing thing for me is that sometimes I have long periods of NO PVCs. The "sometimes" are somewhat rare, and I initially thought---they have gone away--but have learned not to think like that. Still, whatever is happening in the complex cardiac cycle that avoids them (like during exercise) is there at other times. The bummer is that it is not controllable.

I continue to search the web and am delving into the chemistry and electrical aspects...the ****pedia entry on PVCs is an excellent, simplified explanation, along with a list of possible causes and possible "things that might help", and there are a number of links which lead to other interesting and informative entries. Some folks might be interested in checking it out.

Thats a hoot....what forum rule has the wi ki replaced with asterisks?

How about w-i-k-i-p-e-d-i-a... anyway, interested parties should be able to figure out the URL from what is above, else do a google search.

Also how come the url does not render as a clickable link?

My doc says that the PVC's are far more likely to happen when your heart rate is slowing down. Something about the electrical rhythm allowing it when it beats slowly -- when beating fast it overrides it the hearts ability to skip.

My cardiologist told me the same thing - PVCs are much more likely when the heart is going at a slower rate. The fact that PVCs are not controllable, as you stated, Ken, seems to be a major anxiety factor with me. When I don't feel in control, I feel helpless. This limits my life to an incredible amount. Over my life, my PVCs have often gone away completely for years at a time. Once, seven years went by. Other times, it was 2-3 years on average. Now, for the last two years, they have been with me almost constantly. So the older I get, the worse it seems to be getting. What a mystery this is, and what a nightmare.
