# Supraventricular Tachycardias Using Multiple Accessory Pathways

## TL;DR

The paper describes three cases of heart rhythm disorders involving multiple accessory pathways after a previous treatment.

## Contribution

It presents novel clinical observations of supraventricular tachycardias using multiple accessory pathways post-ablation.

## Key findings

- Three AVRT cases occurred using three accessory pathways after His bundle elimination.
- Two AVRTs involved reverse rotation through two right accessory pathways.
- One AVRT involved retrograde conduction through a left pathway and anterograde through two right pathways.

## 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.
