Abstract

Permanent junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular reentrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction. The majority of accessory pathways in PJRT are located in the posteroseptal zone. Few cases of atypical location have been described. We report a case of PJRT in a 72-year-old woman in whom the accessory pathway was located in the left lateral region and treated by radiofrequency catheter ablation.

摘要

永久性交界性反复性心动过速（PJRT）是房室折返性心动过速的一种罕见形式，由一条具有缓慢递减性逆向传导特征的旁路引起。PJRT中的大多数旁路位于后间隔区。仅有少数非典型位置的病例被报道。我们报告一例72岁女性的PJRT病例，其旁路位于左侧区域，并接受了射频导管消融治疗。
