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.
