I'm 66 and I've SVT since 2007. The doctor put me on metoprolol and lisinopril to help control my episodes. It took a couple of months but they've got it to where I don't even have any anymore. Haven't had any in 16 years knock on wood. It'll take you a while to get over being scared that you're going to get an SVT episode whenever you get a little nervous or you work out a little too hard. You'll be fine.
