I am 44 years old. I had a mild heart attack at 33 and a stent put in. I had a single LAD bypass in 2009. In March this year, I had irregular heart beats (PVCS). It felt like my heart skipped a beat, then a strong beat after that. They put in five more stents in my RCA's. I am still having the pvc's, but my cardiologist said it's nothing to worry about. It really bothers me, because its the same feeling that made me go into the ER in the first place. I don't feel that he corrected the problem. I worry all the time that I'm going to die, although the pvc's give me no symptoms. I hate feeling this way. What should I do ?
