I consider Metoprolol mainly a blood pressure and heart rate lowering drug, not particularly good for arrhythmia. Maybe that is what the digoxin
is for. I have taken Propafenone and
Rhythmal (similar) - and
while they have (guess) helped me maintain sinus rhythm, they have never converted me to sinus, it has always taken other measures, electrocardioversion, in my case. Unfortunately, electrocardio.. no longer works on me.
