An Electrical Storm Is Coming!: Ventricular Storm Case Study

A 65-year-old man presented to the emergency department (ED) for evaluation of epigastric and chest pain. On presentation, a 12-lead electrocardiogram revealed a patient in rapid atrial fibrillation (AFib) with anteroseptal myocardial infarction. Treatment of ST-elevation myocardial infarction (STEMI) and rapid AFib were initiated, and the patient was flown to a regional percutaneous coronary intervention center. Two weeks later, the patient presented to the same ED with a LifeVest external defibrillator (Zoll Medical, Chelmsford, MA). The patient received electrical shock in excess of 10 times from the LifeVest prior to ED arrival where he promptly developed ventricular tachycardia (VT). After cardioversion, the VT storm persisted and required multiple cardioversions, resuscitation, intubation, and transfer back to a tertiary cardiac center for electrophysiology studies and internal cardiac defibrillator placement. This case explores the course of a patient's anteroseptal infarction, utilization and description of the LifeVest external defibrillator, and the subsequent visit to the ED in VT storm. It provides insight into the team approach, decision-making process, and managing a complex medical illness. Furthermore, it helps identify methods for emergency providers to improve their approach in both complex and rare cases.
