Abstract

Intraatrial reentrant tachycardia (IART) is the most common long-term, surgical arrhythmia sequela inpatients with complex congenital heart disease. The management of IART is challenging. Medications,catheter ablation therapy, and pacemaker therapy have all been utilized as treatment options. Slowertachycardia cycle lengths and 1:1 atrioventricular conduction provide even more challenges with regard to detection and antitachycardia pacing. We describe the use of the rate response feature as a means of

patient-initiated cardioversion.
