I'm 78 years old; less than a year ago I had a "perfect" EKG and 3 months ago I had a home health checkup that scored a 99 out of 100. Now I have A-fib--no real reason except my cardiologist says it is "common" in my age group! I'm on Cardizem and a blood thinner. The rhythm is still erratic after 5 weeks. I feel best when I exercise daily on elliptical machine and treadmill. I feel worst at night when it seems I can feel every erratic beat in my chest. I take Tylenol Extra Strength (1000 mg) at 8 pm and then again at 2 pm when I wake up--just to get a half-way decent nights sleep. I am waiting for cardioversion! What kind of cardioversion should I get and can I expect that this will be corrected? I am sick of this! I mean really sick of thinking about this!
