I am 63, 4 yrs ago I had all the tests done, Halter, EKG, ultrasound, Echo, and stress test with the med. Everything was normal. I had the tests because I was having PVCs, the doc adjusted my BP meds, I take Diovan 160 hydrochlorthyazide 25 mg and metoprolol 25 mg x2 daily. That solved problem no more PVCs or not that I noticed. Now 4 years later they are back, only when i lay or sit, doc did Ekg it was normal, said not to worry, well they are scary and wake me up and that all I think about. Any ideas why they started or what to do. My BP IS good, my pulse is good, just driving me crazy.
