Class IC antiarrhythmic drugs are widely used for the treatment and prevention of supraventricular arrhythmias. Although they are safe drugs in patients without structural heart disease, proarrhythmia is a potentially serious side effect. We describe the case of a patient who presented a 1: 1 atrial flutter induced by flecainide, which was also conducted with aberrance and left bundle branch morphology. In these cases, the differential diagnosis with tachycardia of ventricular origin is raised, and it is essential to ask about the use of antiarrhythmic drugs.
