Electrophysiologic Study and Surgical Ablation of Atrioventricular Nodal Reentrant Tachycardia: Report of One Case
房室結迴旋心搏頻脈之電生理學研究及手術治療：一病例報告
摘要
房室結迴旋心搏頻脈(atrioventricular node reentrant tachycardia)為造成孩童突發性心室上心跳過速之另一常見疾病。臨床上有時難以用藥物控制。本簡報一十二歲男孩過去常突然發生心跳過快現象。經心臟內電生理學研究證實其房室結有二套傳導束，而造成房室結迴旋心跳過速。經外科手術切除後，心跳過速現象完全消失。然而；手術後有有第二度第一型(Morbitz type Ⅰ)房室間傳導阻礙，此現象於手術後四個月消失。

A 12 years old boy with frequent episodes of palpitation was found, by the electrophysiologic study, to have an atrioventricular (AV) nodal tachycardia. Endocardial mapping during surgery revealed that the earliest retrograde atrial depolarization of the tachycardia occurred at the posterior part of Koch's triangle. Under normothermic cardiopulmonary bypass, perinodal dissection was performed above the tricuspid annulus at the coronary sinus region. The retrograde VA conduction disappeared. Post-surgery the ante grade conduction had a Mobitz type I block which had returned to normal after the fouth month follow-up.
