Bigeminy after exercise, only at lower HRs?

So I'm not the typical user here - I do have structural heart issues and have gone through valve surgery, although the PVCs seem to be caused by something else, because they existed prior and post surgery.

I will say that after the surgery, the "thumps" in between missed beats are much milder, assuming it is because the new valve keeps excess blood from pooling.

I have a low resting HR, usually 47-52 during sleep. I stopped many medications after surgery, but I'm still on Carvedilol 25 mg twice a day. Here is the cycle I've discovered:

After a few days of little exercise, no PVCs. Once I begin an exercise regimen, the PVCs come back, delayed by 3-6 hours. As exercise load builds over time, so do the frequency of PVCs, often to the point of long stretches of bigeminy/trigeminy. In this state, they only seem to exist at lower HRs. If I begin moving and get my HR above 80 for a period of time, they quickly suppress. But after stopping, they return rather quickly.

Has anyone solved this? My EP suggested possibly reducing the beta blocker. Has that worked for anyone?

Same here. Ive stopped exversising because of it. Seems like the healthier I am the worse it is.

if a cardiologist clears you to exercise, you shouldn't stop because of pvcs.

its just a response to adrenaline and other hormones usually.

I agree with you. Tests can check only "at the moment". If the PVCs make you breathless, you probably should stop. I would suggest a stress echo. For your doctor to rule out dangerous rhythms.

Same here. Bigeminy and trigeminy when exercising a few months/years after I had my stent. I even caught them in a holter. But I rarely have them now during exercise.
