I have had pvcs for years but lately have been getting tachycardia that has gotten very annoying & disruptive. It's worse with any sexual arousal or activity for some reason, it feels my heart is going to race out of my chest sometimes if I even think about sex let alone have it. I've had echos, etc, all normal. The cardiologist put me on 50mg Metoprolol several months ago after a rather severe bout of sudden tachycardia. Sometimes I get the tachycardia after migraines & it continues even when totally at rest. But usually it's positional, when I get up suddenly, or like I said, with sexual arousal/sex. I've noticed a decrease in my erections too. The cardiologist said the metoprolol could cause this & that we could try Cardizem if I want. 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. So should I ditch the Metoprolol and try Cardizem? I also want to try and get my erections back. Any ideas? Thanks.
