# Ventricular Fibrillation Arrest Triggered by Antiemetics Revealing an Underlying Long QT Syndrome in a Young Woman

## TL;DR

A young woman's undiagnosed heart condition was revealed when antiemetic drugs triggered a life-threatening event, highlighting the need for awareness of medication side effects.

## Contribution

This case study emphasizes the importance of recognizing antiemetics as potential triggers for cardiac events in undiagnosed long QT syndrome.

## Key findings

- Antiemetics can precipitate cardiac arrest in patients with undiagnosed long QT syndrome.
- Survival is possible if the condition is recognized and managed promptly.
- Clinicians should be aware of QT-prolonging drug side effects to prevent fatalities.

## Abstract

Undiagnosed phenomena such as long QT syndrome can have devastating effects on patients. Our case, involving a woman in her 30s, highlights the serious effects of undiagnosed long QT and how antiemetic medications can precipitate cardiac events that can lead to fatalities. Various medications are known to prolong QT intervals, and clinicians must be aware of the side effects of some of these commonly used medications. While survival was achieved in this case, education and reflection can act as a tool to help improve global standards of care in this subgroup of the population.
