I'm A 46 Year-old Nurse Practitioner. Very Concerned About PVCs/PACs.

I'm a 46 year-old nurse practitioner. Very concerned about PVCs/PACs. Had nuclear stress test one year ago & echo 3 months ago. Both fine. Had holter monitor 6/15 that showed minimal ectopics. Concerned because I did still have some PVCs on the treadmill part of the stress test & I've always heard they should go away with exercise if benign. All cardiologists I've seen say they are benign but still concerned. I also feel them on the treadmill at home.
