Have had PVC’s for 40 years. They started getting worse when AFIB episodes began about 4 years ago. AFIB always stops on its own, but BPM is around 200, and lasts anywhere from 4-12 hours. Sometimes I go 10-12 days in between episodes and other times anywhere from 20-45 days in between. Anyway, many of the PVC’s seem to have shifted to the upper stomach (sternum area), and high up in the chest. Flutters, missed beats, hesitations, with light exertion. This has only been happening the last two months. The PVC’s and AFIB have never prevented me from doing any physical activity I want until lately. Anyone have a clue, or experienced same?
