A tilt table test was positive, and it was also found that I have a lower heart rate
, around 50. I am on lisinopril, 20 mg, for blood pressure, I have adrenal surges and the medicine keeps me from spiking, and have been on the same medicine for about 6 years now. I have been seeing an EP, who has performed a 30 day heart monitor test, ECHO, and stress test, all came back OK he said. Throughout the last 2 months I have had bouts with constant yawning, for it to subside on it's own after a day.
