I am 79 years old...female that used to be in excellent health. I have had some major heart problems with surgery and have not rcovered quickly. I had a pacemaker 8 years ago and then a new one put i 2014. After that I developed AFib and Tachacardia. It was decided that I have a cardio version . That did not work so I then went in for an ablation. That went wrong and I bled out and was in CCU for a week.I never got my strength back and have shortness of breath. Surgery was late Aug. I am short of breath and my legs are weak and I have pain at times. So far no one has helped me. I am in rhythm at this time.
