@anonymous1274 I'm getting the same thing. I've had low heart rate for some time, been on metoprolol for a long time. Now my VA doctor said get off so I did, now the heart rate is running in the 80s, still dizzy like I was with the low heart rate, but now can't sleep, getting headaches. I feel the cardiologist who first denied there were any real problems, in fact dizziness wasn't a heart problem. I feel he's guessing and I'm the guinea pig in this story. Not sure why I'm writing other than I feel trapped in a guessing game by doctors
