I have pcv s throughout my waking hours. They seem to occur randomly, but more prevalent while sitting. One pvc occurs between each normal beat and can go on for hours which becomes very bothersome. I am under cardiologist care and he tells me nothing can be done to return to a normal heart beat. I get very light headed when I get up from sitting and pvc s will not stop until I work hard. He has prescribed a couple of medications (flecainide 100mg and mexiletine 150mg) which both give me nausea. Are beta blockers are possible alternative? What natural remedies can be tried. I have ejoyed a healthy lifestyle for 70 years many years as a 5K to marathon runner.
