I'm not a physician but I'm skeptical that a >30% PAC burden should be considered benign. For one, there's a lot of evidence that a high PAC burden can lead to AF. And my understanding is that even in the absence of AF, those PACs may cause damage, eventually leading to cardiomyopathy. IMO you're correct in getting this addressed and treated. Best of luck in getting this sorted out.

@rusjr well I've had them for 25 years and no heart damage at all, started in my thirties and after 50 they started SVTs and eventually AFIB. Now I'm on this t flecainide 50 mg 5 days now and still have PACs but there more mild. Seeing a EP in 3 weeks to talk about ablation. Echocardiogram good, ekg normal with PACs all the tests normal

@rusjr The research I have seen recently shows the curve adjusting upward slightly for morbidity due to PAC burden at only 3%. It was a slight gradient change, but obvious and given to pause. I agree with you that 30% burden is excessive and dangerous, and I would urge someone with only a 10-15% burden to seek the services of a good electrophysiologist.
