I was in front of my computer last night and was looking at porn and my heart all of a sudden started beating like crazy. I called 911 and they came in my house and put me in the ambulance and said my heart rate was 180 or some crazy number. They got me to calm down and when we got to the hospital they tested me and found nothing except low electrolytes. i am on a test and tren cycle. any ideas what caused this?
