Mary, It sounds like you may have an autonomic nervous system problem. Do you have POTS (postural orthostatic tachycardia syndrome)? Low blood pressure can be just as harmful. Have they determined a cause?

Becky, Yeah, I know, I was about ready to go strangle the radiologist. Ten days of pure hell imagining surgery and dialysis and a much shorter life.

PVC: Premature ventricular contraction. A lovely arrhythmia that is normaly "benign." Mine start going nonstop after only a brief amount of physical exertion. No one, and I mean not even the cardiologist so far, has a clue of why I have hypertension out of nowhere causing these little life-threatening turds.

Thanks for the high-5.

Annie
