Im a 23 year old guy and had an episode 2 weeks ago. 20 ekgs, 2 stress tests, 2 stress echos, echocardiogram, Cardiac MRI, EP study, blood tests and x rays all normal. Still no answer. It was 22 beats long and lasted a few seocnds. I took 60 mg of prednisone a day and a half before, so im hoping that caused it. Is there anyone else out there like me? Worried? Scared? Paranoid?
