Occasionally, in the past, my heart will skip beats. I can feel it flutter in my chest when it occurs and I sometimes get light headed. It usually doesn t last long and stops on its own...During the last week, every day I ve had an episode of my heart beating twice, then skips a beat, and this has been lasting for hours..Today, I took 0.3mg of Alprazolam while it was occuring. I fell asleep for about 2 hours, but then woke up, very drowzy, and yet my heart was still beating at 2, and skipping 1.....There has been a lot of stress in the home lately, and I ve always had anxiety disorder, but my heart doing this is a concern...Got an ideas? Thank you very much!! John
