How long will it take for a blood clot to form during paroxysmal atrial fibrillation?

It Varies. It depends on lots of things - is the patient on a blood thinner (it would take longer)? Most people think it takes at least 48 hours, but some studies have show an increase in stroke with as little as 5 hours of atrial fibrillation.
Paroxysmal Afib. Paroxysmal atrial fibrillation means that it comes on suddenly and then often goes away. Sometimes people can't tell, so it's often recommended to use anticoagulation such as Aspirin or coumadin (warfarin). When and if a clot will form is an inexact science, but is determined by other risk factors, ultimately with your participation in the decision of whether to take medication or not.

During the surgery, the heart must be stopped and blood is bypassed to an external medical device so that blood can be delivered to the body.

Complicated Answer. This is a tough one. If you already have severe coronary disease, fibrillation can produce rapid heart rates which exceed the available blood supply and lead to a heart attack due to "demand ischemia." the same is true, though even more rare for avnrt. Afib, but not avnrt is often a marker of (is seen with) other heart disease which of course puts you at increased risk of heart attack. Read more...
