Paroxysmal supraventricular tachycardias are most commonly due to atrioventricular nodal reentry or to reentry using an atrioventricular bypass tract with or without manifest preexcitation during sinus rhythm.‘m3 These two arrhythmias are usually manageable by antiarrhythmic agents but occasionally require surgical treatment which may involve interruption of one limb of the reentrant circuit (as in the case of bypass tracts), 4* 5 destruction of the atrioventricular junction (for both tachyarrhythmias), 5-g or by specially-designed antitachycardia pacing devices. lo-ll Automatic atria1 tachycardia is an uncommon, frequently incessant, and often medically resistant arrhythmia which is not amenable to pacing therapy. l”* 12-14 This arrhythmia has been managed successfully by indirect surgical approaches aimed at destruction of the atrioventricular junction. This procedure, however, requires pacemaker implantation. There have been only a few reports of surgical procedures directed at the tachycardia itself. 15-17 These procedures have included electrocoagulation, resection, and cryothermal ablation. In each of the reported instances, however, the tachycardia was present at the time of surgery and could be localized by intraoperative mapping. The pathophysiologic substrate for such resistant arrhythmias has not been reported. In the present case we report
