he said it may be due to the a-fib itself, or past alcohol
abuse. It was not enlarged, and
the valves were ok...but, all I'm doing is thinking the worst, and I'm only 51 and have been active all my life. Just took a 2 mile walk....but, I feel very low and with no energy....side effects of the toprol which slows down the heart. I just want to feel myself.....any suggestions or comments?
