Hello: I am a 61 year old male in generally good health except for idiopathic paroxysmal atrial fibrillation.I am being treated with daily Monocor and 325 mg ASA. I was diagnosed in 1984,and I get about 1-2 attacks a month.Most times it auto-converts to sinus rhythm in about 12 to 36 hours.
On those occasions when it doesn’t resolve on its own,my cardiologist has given me a prescription for Flecainide (300mg) to take as required.
The reason I am writing you is that when my attacks begin,they are often quite debilitating,(I have fainted going to the bathroom in the night on a couple of occasions),but after a period of 12 hours or so,they become almost asymptomatic,with the only indication being a thready pulse.I am at that point capable of brisk walking, for example,without difficulty.
So my question is: Am I at risk of clot formation when the arrhythmia is largely asymptomatic? As I write this,I am experiencing an episode which began on Thursday last,and seemed to revert to sinus rhythm last night(Saturday),but has since reoccurred asymptomatically as a thready pulse,and I have taken the Flecanide.
I would (and plan to) discuss this with my cardiologist,but living in Canada with it’s socialized medicine,it is very difficult to get to speak with him.Sorry to be so long winded!
I don’t think your treatment is adequate. I am also concerned about the risk of clot formation and stroke. Your AF is very symptomatic, and thus cannot be followed with the present regimen alone; you should consider an ablation.

Hope this helps,
