My experience with a beta blocker (Metoprolol
) found it did squat to prevent them. It did make then easier to convert. I got 3-5 episodes per month.
Will it be successful? Well that depends a lot on what kind of SVT it is, and where it's exactly located. But the odds are in your favor.
Stick around and let us know how you make out. It's a piece of cake, very little pain, and you're up and around the next day.
