What percentage of patients with non-sustained focal atrial tachycardia detected on an outpatient Holter develop paroxysmal atrial fibrillation, and how should we identify and treat patients at the highest risk of progressing to PAF?

I agree with most of the points by Dr. @Dr. First Last. I'll go through my train of thought from monitoring to what the %age is (PAT progressing to PAF) to afib management/reasons we care. Apologies for the length of response:

1) The right monitoring technology should balance what you are looking for...

It is intuitive to think that focal atrial tachycardia would lead to increased risk of atrial fibrillation. However, the basic mechanisms of the two arrhythmias are quite different. There is not necessarily a clear answer to the question regarding the incidence of atrial fibrillation and in fact, it...
