I had my second ablation 15 months ago and i have experienced some problems that my doctor does not seem bothered about. I have been getting 1 missed heart beat on average every minute for the last week and it occasionally goes very fast for a few seconds before returning to normal. It has done the later about once a month since the ablation, and you feel as if you are about to die as it is a strange sensation. My concern is that because it is paroxysmal they rarely catch it on ECG so, are reluctant to test. Should I be concerned?
