I awake short of breath, my ears begin to ring loudly, I get a tingly feeling in my chest, and my heart starts to
race.
After the episode I shiver uncontrollably, have an upset stomach, and feel nauseous. I've worn the holter monitor but haven't caught an episode. I also had an echocardiogram and a stress test which yielded normal results (but was still on my beta blocker which, I feel, masked the problem).
