I am a 49 year old female, in pretty good physical shape, although 20 pounds over weight. I have just been diagnosised with "left ventricular dysfunction" and EF with a 30-35% output, and my heart shows PVC on top of that. I have had several test and still going through more. My question is how serious is this? I do not smoke, I drink very little, but I do have a lot of family history of heart problems.
