Better use medtronic adapta or advisa, for paroximal AF patient? I had heart ablation n it was failed, I'm still on AF

Neither. Neither Adapta nor Advisa is really an atrial fibrillation treatment device, just "overdrive" atrial pacing, which reduces a. fib. burden. You may want a defibrillator which treats a. fib. like the Evira ICD which can deliver a low grade 50 Hz jolt (you won't feel) or even a shock in the middle of the night, which you will feel, but will get you out of a. fib. Or consider another ablation.
