About a couple of months ago I would occassionally get episodes of rapid heartbeats during my rides. It was bad enough that I would have stop for a few minutes to let my heart rate return to normal. This started happening more regularly, so I went to see a cardiologist. I was diagnosed with paroxysmal supraventricular tachycardia, or PSVT.
The doc tells me that there are three treatment options:
1. Do nothing. For the most part I've been keeping the episodes under control by keeping my heart rate below 150 (oh, I'm age 37, BTW). But even then the doc said the episodes may start becoming more frequent over time.
2. Medication. Either beta blockers or calcium channel blockers. My first doc gave me beta blockers (atenolol, 25 mg). The side effects were pretty bad, including impact on exercise performance since the drug limits heart rate. I dumped this doc, since he just gave me these pills without warning me of the side effects or telling me there were other treatment options.
3. Catheter Abalation. A procedure that eliminates the short circuit that causes the rapid heartbeat.
I'm leaning towards (3), anybody have experience with such a procedure?
