摘要

简介：慢速房室结通路（SP）通常只有一个心房突破点：我们报告了一例在心动过速时有两个不同心房突破点的快慢型房室结通路病例。最早的心房激活点（EAAS）位于右侧下间隔，其次是三尖瓣环的下外侧壁。对 EAAS 的消融将其转移到了下侧壁：本病例表明，房室缺血性心律失常患者的单个 SP 有两个不同的心房突破点。

Two Distinct Atrial Breakthroughs During Fast-Slow Atrioventricular Nodal Reentrant Tachycardia

Introduction

The slow atrioventricular nodal pathway (SP) typically has a single atrial breakthrough site.

Methods and Results

We report a case of fast-slow type AVNRT with two distinct atrial breakthrough sites during tachycardia. The earliest atrial activation site (EAAS) was at the right inferior septum, followed by the inferolateral wall of the tricuspid annulus. Ablation at the EAAS shifted it to the inferolateral wall.

Conclusion

This case demonstrates two distinct atrial breakthrough sites from a single SP in AVNRT.
