I am a 49 year old female. I have been experiencing flutter in my chest . This happened a year ago and I went to the ER. They did an ekg and sent me home saying they were benign. I followed up with my GP who sent me to a cardiologist . He didn t think anything was wrong. After a few weeks they went away. Two weeks ago they started up again and have increase in intensity. Last night they actually kept me awake all night and have continued constantly today. I have taken a Xanax in hopes it was stress related, which has increased due to the death of a friend. It didn t seem to help at all. But they are driving me crazy and I am hesitant to go back to the doctor if t is really nothing. I don t think its really my heart. I went on a two mile walk last week while they were happening and they didn t go away or get work. Any suggestions?
