Why does stressing the heart with exercise can trigger more frequent extra beats (PVCs) afterwards for a month or more?

I’ve read that it might be caused by some defective heart muscle cells (cardiomyocytes) giving random electric impulse firing at wrong times and they die off eventually and ectopic beats disappear when it happens.

Is this true?

I have no real idea but if your heart is doing weird shit see a doctor. As someone who has a heart condition becuse none of the symptoms were a big deal until they were, the precaution is worth iit even if the doctor says it’s no biggie.
