# Bidirectional Ventricular Tachycardia Secondary to Dichloromethane Intoxication: A Case Report

## TL;DR

A 30-year-old woman developed a rare heart rhythm disorder after accidentally ingesting dichloromethane, a chemical solvent.

## Contribution

This is the first reported case linking dichloromethane intoxication to bidirectional ventricular tachycardia.

## Key findings

- The patient developed BVT and cardiac arrest after dichloromethane ingestion.
- No structural heart disease or electrolyte issues were found, implicating the chemical as the cause.
- This case suggests a new potential trigger for BVT.

## Abstract

Bidirectional ventricular tachycardia (BVT) is a rare ventricular tachyarrhythmia, and only a limited number of etiologies have been described to date. We report the case of a previously healthy 30-year-old woman who developed BVT followed by cardiac arrest after accidental ingestion of dichloromethane, an organochlorine solvent used in illicit volatile inhalant preparations. Further evaluation revealed no structural heart disease, electrolyte disturbance, or exposure to medications classically associated with BVT, supporting dichloromethane intoxication as a plausible and, to our knowledge, previously unreported trigger of this arrhythmia.
