I struggle with an anxiety disorder, and a few years ago I started to feel like my heart was skipping a beat. I went to the doc and he told me it was palpitations. But, what's the real definition? Some say palpitations are a racing heartbeat, others say it is your heart skipping a beat. Anyway, when my heart feels like its skipping a beat, I get short of breath and sometimes I get a throbbing in my head for the moment. Anyone else of irregular heartbeat? I have had several EKGs, 2 holter monitors and a 2decho, and everything is normal. However, I can't stand the palpitations and the way I feel when I get them. Any adivse or help? Could it be just the anxiety? What can I do to relieve the palpitations?
