Judy - How long ago were the echo and stress test performed? If not in the last couple of months, then I would seek a reputable cardiologist and have them redone. I had problems a year and a half ago that were resolved and recently I have had new problems develop. Things can change. EKGs don't always show the problem. All mine were normal too, but my echo and stress tests were a different matter altogether. I am concerned about your pressure/pulse droping that low, mine did this about a year ago and I had mini-strokes/TIAs back then. Never found the cause, but they tested my prothrobin and throbin times (PT & PTT tests) and I wore a 24 hour holter monitor. They were okay though, but you should still have yours checked.
I would contact a reputable cardiologist and go over everthing with him/her. Could the heart block get worse? Could it be significant for a larger problem with the heart not functioning properly? What you describe sounds suspect, so your concern is warranted. The ER probably won't do anything unless it is an actual heart attack and shows up in bloodwork or on the EKG. My guess is to seek ar cardiologist and/or if you already have one to seek a second opinion. Perhaps there are medications that could alleviate your symptoms even if your heart is okay.
Let us know how you make out. Best wishes - Kristin
