Ivabradine as a treatment option for junctional ectopic tachycardia in an adult female

AbstractA Junctional ectopic tachycardia diagnosis was performed using two electrophysiological maneuvers in an adult female with a narrow-complex supraventricular tachycardia with a bystander AV-node slow pathway conduction, who previously underwent catheter ablation attempts for an atrio-ventricular nodal re-entrant tachycardia misdiagnosis. The first maneuver was atrial entrainment with an atrial-His-His-atrial response. The second was based on the response to a premature atrial complex delivered at different phases of the tachycardia cycle confirming that anterograde slow pathway conduction and retrograde fast pathway were not involved. Considering that verapamil, diltiazem, bisoprolol  + flecainide, and nadolol were ineffective, we tried ivabradine with no sustained arrhythmias during 18-months.
