I should also point this out.

1st episode - lasted about 24 hours
2nd episode - lasted about 12 hours
3rd episode (current episode)- I've been in afib for 5 days.

I talked to my cousin over the weekend, and apparently, his afib is very similar to mine in that his heart rate is relatively low, he has no other symptoms, and he has no prohibitions.... I asked him "then why do they want to return you to normal sinus rhythym?" he said, "because I've been in continuous afib for over a year and my docs tell me that the atrial chamber will dilate if you're in afib too long."
