Another thing that helped me...I went to therapy for a while and took ativan when I needed it. Worry and stress worsen any kind of palpitations.
A few years ago I had almost daily episodes of irregular heartbeats, racing heart, beating up to 190 beats per minute and a couple of episodes of a fib. I was in the ER 6 times in a 3 month period and was admitted to the hospital once. I was totally freaked out and obsessed about my heart. I was scared to be alone, afraid to go anywhere, it totally took over my life. I was miserable. On my last visit to the ER, this nurse really pissed me off..she asked me if I didn't have anything else to think about except for my heart. I thought about it later and realized she was right, that was all I was thinking about. So I started forcing myself to go out and do things..just little things at first. Then I started going to the Y to exercise, and little by little I got better, got most of my life back. It's been 6 years now and my heart will still act crazy sometimes and it scares the crap out of me. I don't think I will ever get back to not worrying about it some, especially if it's acting particularly stupid. But you really can get back to normal life functioning. It's hard and you really do have to force it. But you can't let the fear and worry win.
Most defiantly. About two years ago I started having fluttering palpitations and it caused my to have anxiety and panic attacks so bad that I can't even leave my house now. I have palpitations all the time and I went from being an extremely athletic and outgoing college freshman to now I never leave home. I'm so desperate for help and I feel like I'm going to die any day
