“Double fire” is generally characterized by 1:2 atrioventricular conduction of sinus beats traveling down fast and slow pathways that result in double ventricular response. When this phenomenon repeats rapidly, dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) occurs. We report a case of an irregular tachycardia with a comprehensive record that includes an electrocardiogram, a transesophageal electrophysiology study, and an intracardiac electrophysiology study. This is the first report of transesophageal electrophysiology study in the diagnosis of DAVNNT. A diagnosis of DAVNNT was deduced, and the patient was successfully treated with radiofrequency ablation of the slow pathway.

双房室结不折返性心动过速的经食管电生理研究

“双火”通常以 1:2 的房室传导为特征,窦性搏动沿快慢通道传播,导致双心室反应。当这种现象快速重复时,就会发生双房室结不折返性心动过速 (DAVNNT)。我们报告了一例不规则心动过速的病例,其综合记录包括心电图、经食道电生理学研究和心内电生理学研究。这是经食管电生理学研究诊断DAVNNT的第一份报告。推断出 DAVNNT 的诊断,并成功地对慢通路进行射频消融治疗。
