So I'm extremely concerned about my heart. My blood pressure has been in th 170s and 180s for a week now. Right now it was 184/94. Last time I was here the admitted me and did a stress ECHO. Funny how that my Blood pressure only went up to 178/68 on the treadmill and my HR was 162. These test came back normal. Now I can't sleep at night because my heart beats so hard that it rocks me. I only weigh 145lbs. I'm very concerned and on the verge of a breakdown. Don't know what to do I usally exercise every day doing briso walking @ speed's of up to 4.8mph on good days for 20-30 minutes. I always do a minimum of 2 miles of brisk walking. What gives? I really think I'm on the verge of dying.
