I really don’t feel anything just had a EKG before hand surgery after an injury and it showed PVC’s. I have had EKGs yearly for years…never a problem. I have not had caffeine for about 8 months, I just decided to stop, it was months before the abnormal EKG. Was referred to a cardiologist and prescribed medicine. Still having “too many PVC’s”. Now I’m being referred to an electrophysiologist.
