I am a relatively fit 52 year old who has had PAF for about 9-10 years now. It was infrequent when I first noticed it and did not know what it was until about 5 years ago when I started getting it about every 3-4 months. Now it's on a 2-3 week schedule, lasts anywhere from a few hours up to about 10. Doctor has me only on a low-dose aspirin, no other meds. I am having an ablation on March 3. I am told I don't really need to have it done because the only risk is stroke which is very low given my other risk factors. I run about 25-30 miles a week. Pushing the running (I am an age-group semi-competitive runner), stress, alcohol, and caffeine seem to be my PAF triggers. The cardiologist says that the ablation should allow me to get back to where I can do speed work again. Don't care about the caffeine or occasional beers. Anyone out there able to re-start the speed work after an ablation?
