I have read frightening articles about Flecainide such as sudden cadiact arrest and having a high chance to have a worse and fatal arrhythmia by taking this after certain time. Since I am taking this medication( it is about a month) my heart beat are back to normal and I feel good and do my daily exercise and feeling good. Back every day I think this is not going to last and something bad is going to happen and I might have heart attack sooner or later. BTW, I am a fit 69 years old woman very active, loving traveling and have no other heart issue or problem. Please advice
