Lately I am getting worse tachycardia even with the 50mg
metoprolol twice a day. It seems to come and go in bouts. Overall the
metoprolol has helped my tachycardia a lot in the several months I've been on it, but I wonder if it's run its course since the tachycardia seems to be coming back somewhat.
I'm only 33, in decent shape, about 178 pounds, 5'11, a bit out of shape but not terribly. I tend to not tolerate exercise too well in that it triggers my tachycardia at times.
