For someone not on medication, a common Pill in the Pocket is 100mg Flecainide + 1.25 to 2.5mg Bisoprolol (your doses may be different). I know you can stop and start a small dose of bisoprolol. But, ten days ago I had an example of repeated attacks of AF/Tachycardia. The PIP worked against the first attack on Friday, I continued on Flec + Bisoprolol in order to keep the lid on things on Saturday and Sunday, then another attack, tachycardia (fast regular 132) struck, it later went up to 155. This tachycardia overcame the protection of the Bisoprolol. I decided at that point to let it run without extra medications so as to provide the doctor with a clean slate. I saw the doctor 28 hours later.
Given the problem that Bisoprolol cannot just be stopped, why then is it used in PIP instead of Verapamil?
I have reasons for asking -- I am not always in a position to see a doctor quickly.
Has anyone else had to cope using PIP with repeated attacks of AF in a short time?
