Hi, I had CABG surgery and 5 bypasses in March 2018. Since that time, I have been on 50 mg of metoprolol tartrate twice a day. About a month ago, was feeling lousy, some dizziness, fairly low pulse (low to mid 50’s). Did bunch of tests and stress test, and determined dose was too high, so initially cut dose in half. Went back and cut dose in half again, then went for ekg last week and cardiologist took me off it completely. Now noticing my resting pulse is now in the 70’s and 80’s (much higher if I do small exertions). Have to go back this week to wear holter monitor for a day. Just trying to get info on side effects of getting off this med. Feeling ok...not great. Thanks.
