Hi friends, I am having a really rough time with tachycardia and an irregular heart rate today. Last week I had an EKG, echo and a 24 hour monitor test but have not received the results yet (appointment tomorrow). The doc had given me a beta blocker to try, but the side effects were to tough to handle and increased my pain a bunch. I am sitting here almost panting and am still having a very uncomfortable chest. Any advise on what to do or what has worked for anyone else would be appreciated. I hope all are having a good night and much thanks, Lisa
