While flecainide is an effective antiarrhythmic medication for managing conditions like atrial fibrillation (AFib), it carries a notable risk of causing a different arrhythmia, known as atrial flutter. This paradoxical effect, often referred to as proarrhythmia, is a critical consideration in clinical practice and for patients undergoing treatment.
