Hi, I have palpitations from time to time. Since I was 15 I have had anxiety and panic attacks. I now take paxil, synthroid, lipitor and norvasc.I am approx 60 pounds overweight, I do not smoke or drink.I have in the past 2 years had a heart monitor on for a month, and had cardiac ultrasound. Everything comes back normal. When.I get the palpitations I do not feel faint, it is just annoying.I have had them from stress but I do drink coca cola and I like chocolate.I haven t had a pop since two days ago and I had one piece of chocolate today. I am not stressed today but I am having palpitations on and off.I am 64. Both my mother and my maternal grandmother ended up with pacemakers. I do not exercise often enough but I am starting to try and exercise every day for 30 minutes.Am I destined for a pacemaker or is there something I can do to help myself?
