摘要

一名 51 岁的女性反复出现心悸。心电图显示窄QRS心动过速，短RP构型。计算机断层扫描显示冠状窦（CS）闭锁，并伴有一个小的持续性左上腔静脉（PLSVC）。电生理学研究发现，逆行性最早心房激活点（EAAS）位于CS骨膜处，但无递减特性，副希氏起搏提示逆行性房室结传导。使用 1.6-Fr 微电极导管经由 PLSVC 远端置入 CS，证实 EAAS 位于左心房，而非 CS 腔。经房间隔入路发现了左外侧辅助通路，并成功消除了该通路。

Elucidating left atrial electrical potential with microelectrode catheter: A case of coronary sinus ostial atresia with small persistent left superior vena cava.

A 51-year-old woman presented with recurring palpitations. Electrocardiography revealed narrow QRS tachycardia with short RP configuration. Computed tomography showed coronary sinus (CS) ostial atresia along with a small persistent left superior vena cava (PLSVC). Electrophysiological study identified the retrograde earliest atrial activation site (EAAS) at the CS ostium without decremental properties, and para-Hisian pacing suggested retrograde atrioventricular nodal conduction. Using a 1.6-Fr microelectrode catheter distally placed in the CS via the PLSVC, EAAS was confirmed within the left atrium, not the CS ostium. Transseptal approach revealed a left lateral accessory pathway, which was successfully eliminated.
