I have heart problems, manifested as irregular heartbeat. As far as I know, we are talking about ventricular arrhythmia. I was told it is a serious condition that could threaten my life. I am scared so I have decided to pay more attention to my health. What is the mechanism of action of propafenone?

Actually, propafenone is an anti arrhythmic. It affects the transport of nerve impulses through the heart, slows down the same thing, blocks Na channels and after higher dosages, it can also affect Ca slow channels. In this way, it slows down the transportation of these ions through these channels. I hope this helped a bit.
