Ventricular fibrillation due to coronary vasospasm triggered by hyperventilation in a patient with panic disorder: case report.

ABSTRACT:

Background

Panic attacks can trigger hyperventilation, which has been associated with the induction of coronary vasospasm. The resulting vasospasm may cause myocardial ischaemia and trigger life-threatening arrhythmias. Patients with panic disorders experiencing hyperventilation sometimes present with symptoms similar to those of acute coronary syndrome, making it difficult to determine their origin.

Case summary

A 37-year-old man with a history of panic disorder was transported to our institute after he experienced hyperventilation during a panic attack and developed chest pain and a subsequent loss of consciousness. During transportation, ventricular fibrillation was observed on electrocardiography, and sinus rhythm was successfully restored with defibrillation. Suspecting
