I am a 31 year old male, 6'4, 195lbs. I visited a cardiologist in April 2010 because of palpitations during exercise. I had an echo done: trace mitral and tricuspid inefficiency, EF 53%, borderline global hypokinesis (my left ventricular motion is borderline reduced, but structurally normal). Overall, the doctor said I was fine but hypertensive, so he put me on 10mg of Ramipril for my BP. Recently, I've had continued issues with anxiety during exercise and palpitations. So I was told to come in for another stress test. I took it and they saw ST depressions. The doctor (not my regular cardiologist) stopped the treadmill, but after he looked through my file, we resumed. Overall, I was fine and he suspected a false positive, but I still had to go in for a nuclear stress test. Pretty much the same thing happened with my heart rate, though I do not know if there were more ST depressions, I'll find out Monday. Both cardiologists suspect it is my anxiety. I recently had an "angioscreen," and everything came back normal. Also, my cholesterol is 137. I was taken off of the ramipril and put on 12.5mg of metoprolol twice a day. I started Monday and my heart rate hardly ever goes above 60 bpm; even standing and when I walk at a normal pace it stays in the 70's. I can't go for long walks without being exhausted, though today I was happy that I managed to get my heart rate up to 102 (at that pace it normally would have been at 118-124). I'm feeling tired often. Are these side effects temporary? I'm starting to wonder if my cardiologist will take me off of the beta-blockers. It kind of *****, because it has helped with the anxiety aspect of my health, but I can't deal with feeling run down all of the time.
