Heart felt like it was fluttering/shuttering for about 1 minute, I started feeling like I might lose consciousness and my face felt very flushed and hot. Feeling better now, heartbeat seems normal but very weak w/ a headache. I've had a history of a sudden rapid heartbeat and have made a few trips to the doctor/ER, stress test done with nothing showing out of the ordinary. This episode scared me more than the others but don't want to go ER again just to be told everything is fine and sent back to the same specialist.
