I have my first appt. with a cardio tomorrow because of heart palpatations that started 2 weeks ago. The first night I had terrible indigestion and my heart starting racing then subsided then racing again several times. I also felt very anxious like adrenaline was rushing through my body. I went to the ER, but they said my heart was fine. I was okay for a few days, then it started up again and has been non-stop for over a week - every day, the symptoms being worse at night and early morning, with a high HR of 70-90 (normally mine is low 60's) with these surges every 15-30 minutes all night. I am losing sleep I can hardly eat and my stomach is very acidic. I've given up caffeine and alcohol. My GP gave me Atenolol until I could get in to see the cardio, but all it's done is slowed down the symptoms, but I'm still getting the waves. I was convinced something is wrong with my heart, but after reading some of these posts, I'm wondering if it's GERD. I hope my Dr's can figure this out. Any suggestions when I see the cardio and follow up with the GP? BTW I'm 46, a runner, slim, always have been healthy. My father died at 64 of a heart attack, but no other heart disease in the family (he was a smoker).
