Okay so I have pvcs and I have had holters, ecgs and echos. Cardiologist says I'm fine abd not to worry. But my pvcs come from the left ventricle and after googling all day I found that benign pvcs come from the right ventricule and less commonly from the left. Now I'm scared that I have something and the doctors just missed it. Does anyone have pvcs that come from the left ventricle?
