Hi I'm Brendan and I have Atrial Fibrillation and want to know how to convert it back into a steady rythym

How do I convert my heart back into a steady rythym

You see a Physician, get tested and take the medication as ordered.

I answered your other thread - you see a Specialist, have testing, take the prescribed medication.

I do take the medication and I have been tested

You may have to have an ablation, but only your doctor can tell you that for sure.
