Well, this 79 year old "girl" hears you loud and clear. We have to keep moving and living our lives to the best of our abilities. Any exercise is worthy! And I was worried that at my age if I needed an ablation, they would say that I am too old for the procedure. However, my appointment with an electrophysiologist was very reassuring. He told me that age was not a factor and if I needed one, he would certainly approve it! So don't get discouraged. I had an arrhythmia for four weeks on blood thinner until I got cardioverted and I am doing pretty well so far. Lifestyle changes may help but they are also not the complete answer. Just take care of yourself and don't let age define your quality of life!
