Sorry if this is too much prying into your health, but what was the personal/medical verdict on whether to continue the running? You say that the symptoms disappear after a while without exercise, but if it’s benign will you keep it up?

I'm going to take it easy for a few weeks, just out of abundance of caution; just in case there's something else that got missed.

I'm not into any competitions or races. I run for health purposes only, so I'm okay losing some fitness. If the symptoms disappear, I'll certainly ramp up again. If they don't, I'll play it by ear :)

My understanding is that 35-50% of endurance athletes have what I have (including symptoms), and they continue to train without any harmful effects.

Thank you for sharing this! I'm into endurance cycling and had similar issues. I'm diagnosed with PVC as well and rely on medication to keep it from happening. I nearly fainted while driving a car, so it is not without "harmful effect".

In my case, the PVC disappears during exercise and comes back when I take a rest after exercising. I just wonder if you had any comparisons between rest vs. elevated heart rate scenarios. Now I'm super curious how elevated heart rate might change the clock rates for those nodes.

Mine is exactly like yours. During exercise it disappears. Then after about 5 minutes post-exercise, the symptoms become even more regular. I'd get 4-5 normal beats, and then a skipped beat. I managed to capture an ECG post-workout and it shows very clearly the regular PVCs: https://dvassallo.s3.us-west-2.amazonaws.com/twitter/F7yWouK...

From what I've read, when we're exercising (or sick or stressed) the heart rate gets overridden by the SNS (part of the autonomic nervous system). The SA node can only maintain resting heart rate, and once there's extra demands from the body, the SNS takes over (controlled by the brain, but involuntary).

It seems to be a good sign that PVCs disappear during exercise based on the studies I found.

I have the same problem. In my case PVCs at rest typically arose the next day after the workout. The only solution for me was to quit exercising for 1 month completely and letting the heart calm down at a max pulse rate of 100 during the day. It seems that the heart then shrinks a bit in size and the PVCs disappear. Then I started to work out slowly again and they didnt appear any more.

Could you share how you cope with all these findings and experiences, psychologically? I have anxiety that my heart is going to stop any moment (even after stress test came back ok), hope you can share your coping mechanism is any, thanks

Where did you get those numbers 35-50%?
