Hi! can exercise cause heart flutters (pvcs)? i've had echo, ekgs, holter, event, but no stress test. cardio cleared me. what is this? thx

PVCs: PVCs can occur at any time. They do not necessarily occur due to exercise. They are more interesting when they occur very very frequently, especially after someone has had a heart attack. Your normal testing indicates you are in good shape! http://www.mayoclinic.org/diseases-conditions/premature-ventricular-contractions/basics/definition/con-20030205
