Hello, Yesterday I had an incident where after I lifted weights my heart rate would not drop. Well after ten minutes I panicked and had to go to the hospital in an ambulance where my pulse was 140/150 sustained and started to drop after about 15 minutes (25 minutes overall). BP 140/90. I had a yogurt in the morning and a banana to eat, and lately I have been noticing that I have begun getting panicky or had rapid heartbeat after lifting only. Typically it goes away but yesterday was different. My EKG was fine and my BP dropped to 131/75 within a half hour. I also have had some heart palpitations lately, and have not felt as strong at the gym. Havent really had shortness of breath or chest pains, although I think during one palpitation I had a slight pain in left chest. I am 33 years old 160 and physically active. Do you have any idea why only lifting would cause panic, and then this episode with my heart. I have an appointment Monday with a cardiologist but wanted to touch base firs
