No way to tell: There's no way to answer your question for you individually. The answer depends on the dose, duration, & individual sensitivity to flecainide. Not every patient responds the same way to the same drug, even if its the same dose. Best way to answer is to talk to your cardiologist or doctor, & compare heart rate results from before you started taking flecainide. If no other data available, testing?
