# Managing a ventricular tachycardia storm: Looking beyond the horizon

## TL;DR

This case study explores managing a severe heart rhythm disorder using advanced mapping and catheter techniques.

## Contribution

The paper introduces a combined strategy for managing unstable ventricular tachycardia using multiple mapping techniques.

## Key findings

- Nonischemic cardiomyopathy can coexist with coronary artery disease.
- Unipolar and isochronal mapping helped identify complex isthmus structures.
- Multielectrode catheter positioning improved outcomes in unstable VT cases.

## Abstract

The case highlights the possibility of nonischemic cardiomyopathy in patients with coronary artery disease and the complex nature of the isthmus with multiple entry and exit points. A combination of multiple strategies, that is, unipolar mapping, isochronal late activation mapping during sinus rhythm, and positioning of a multielectrode catheter at the putative isthmus during VT induction in the case of hemodynamically unstable VT, was used to achieve a successful outcome.
