# Highlighting the Importance of His Bundle Potential During Tachycardia and Ventricular Overdrive Pacing

## TL;DR

This paper explains how His bundle potential helps distinguish between two types of heart rhythm disorders during specific pacing techniques.

## Contribution

It identifies His–tachycardia dissociation as a key diagnostic marker for differentiating AVNRT from NF-ORT.

## Key findings

- AVNRT and NF-ORT can both occur with HV block.
- His–tachycardia dissociation during ventricular overdrive pacing is critical for diagnosis.

## Abstract

Both AVNRT and NF‐ORT can be sustained with HV block. His–tachycardia dissociation during ventricular overdrive pacing is a key finding for differentiating AVNRT from NF‐ORT.
