# Electrogram Dynamics at the Site of Ventricular Tachycardia Termination During Radiofrequency Ablation

## TL;DR

This paper discusses how radiofrequency ablation can successfully terminate ventricular tachycardia by targeting specific abnormal circuits in the heart.

## Contribution

The paper introduces unique catheter ablation techniques that demonstrate electrogram evidence of tachycardia termination.

## Key findings

- Three cases showed successful VT termination using specific ablation techniques.
- Abnormal circuits within the cardiac layer were effectively localized and targeted.
- Electrogram evidence confirmed the termination of tachycardia during the procedure.

## Abstract

Ventricular tachycardia (VT) is a life-threatening arrhythmia associated with high morbidity and mortality, particularly in patients with structural heart disease. Radiofrequency ablation is an effective procedure to treat patients with this malignant arrhythmia. We report three cases of successful termination of VT using unique catheter ablation techniques. Through these cases and techniques, we highlight the advantages of specific localization of abnormal circuits within the cardiac layer involved, as well as electrogram evidence of tachycardia termination.
