I went to the e.r. the other night with tachycardia (160 heart rate) high blood pressure (140/97), dizzyness, weekness, near faint, and couldn't walk cause I was shaking so bad. My blood sugar was fine. They ran so many test (blood test for numerous things including thyroid, did ekg, a vq (or somethinglike that)) and many more that I can't remember. I spent 14 hours they and they couldn't find anything wrong yet everything went back to normal. I have had this happen about every other day for last 2 weeks. Anybody ever had this happen to them or have any ideas of what it may be?
