Supraventricular Tachycardias Using Multiple Accessory Pathways

Key Points

Three atrioventricular reciprocating tachycardias were induced using multiple accessory pathways.
Two of these tachycardias involved reversible pathways that exhibited intricate conduction behaviors across the heart.

Structured PICO

Population

Patient(s) with atrioventricular reciprocating tachycardias (AVRTs) using 3 accessory pathways (APs) and previous His bundle ablation

Outcome

Electrophysiological characteristics of the AVRT circuits

This report demonstrates complex AVRT circuits utilizing multiple accessory pathways in the absence of normal His-Purkinje conduction.

Abstract

Three atrioventricular reciprocating tachycardias (AVRTs) using 3 accessory pathways (APs) occurred with the His bundle eliminated by the previous ablation. Two AVRTs using 2 right APs rotated reversely, and the other AVRT was one with a retrograde conduction through the left AP and anterograde conduction through the 2 right APs.
