question: I am a 64 year old female in what I thought in pretty good health. I am taking Toprol for blood pressure among other vitamins etc. A week ago, while on vacation, I notice I was having an irregular heartbeat and was getting dizzy while standing. I have had pvc in the past and they would go away when I stopped caffeine. My cardiologist told me today that the EKG done i his office a few minutes ago I was in v fib. He said if we had caught this within 48 hours of its beginning, shock could have helped. This afternoon he has put me on Pradaxa for he feels I may have formed a clot in the heart. My pulse irregular is about 80 beats a minute. He has scheduled an echo and stress test tomorrow. There are so many questions I have and did not ask. Is this condition treatable, am I being ultra scared that I think I will die very soon from the silent killer , what about stokes? I know you may not be able to answer this questions, but any information may help. Also, would a couple shots of Scotch hurt?
