A question for Dr Elbaz- Thank you for a great talk. This is a bit off topic, but with respect to a fib, is there a relatively good sense of how long it takes to be at risk for a clot/DVT in someone with paroxysmal a fib? For ex- if you go in and out of a fib, duration less than 8 hours, or 24 hours, is there a significant risk for clot formation? Or does it need to last a minimum of 48 hours? ( When I say in and out, I don’t mean frequently. Maybe 1-2 times/year.) Does age also factor into this? I am assuming these pts would be in reasonably good health. Maybe inc BP, but no CAD, no DM, no CKD. In these pts is pocket DOAC/ beta blocker a reasonable therapeutic response? With thanks.
