Junctional ectopic tachycardia (JET) defined as a tachycardia arising in the atrioventricular (AV) junction with very rapid ventricular rate is notorious for refractoriness to drug therapy. A child with incessant JET was treated successfully with intravenous α-adrenergic blockade. Because of gastrointestinal intolerance to the high dose of this agent, radiofrequency energy was used to catheter ablate the JET without inducing complete AV block.
