@veronica0127 The blanking period typically runs about 10 weeks from the date of the ablation. Some EPs leave their patients on the medications they were on, maybe at a reduced dose, for much or all of the blanking period. This includes AADs, anti-arrhythmic drugs like flecainide or Tikosyn, even propafenone (Rhythmol). About the 12-week mark or so, you would be invited to wear a Holter monitor or similar device for up to 24 hours, but often it's a mid-afternoon pickup and fitting and you drop it off near noon the next day. You record on a sheet provided all significant events, meals, snacks, exercise, anything that you know might 'set you off' with a rapid heartbeat, but with the time included....when each started and stopped. This way they can match up any blips of arrhythmia, if they occur, with a significant stressor or event.

I am not an expert in this and have no medical training. I would think, and hope, that an EP assigning you a Holter monitor would want you off all rate control and arrythmic drugs at least a full week beforehand. You would want the Holter to see the unvarnished heart you really have post-ablation, warts and all. NOT being babied by the drugs!
