Coronary vasospasm-induced polymorphic ventricular tachycardia: a case report and literature review.

INTRODUCTION

Coronary vasospasm is an uncommon but important cause of myocardial ischaemia and ventricular arrhythmias.

CASE PRESENTATION

In this report, we present a striking example of vasospasm manifesting as ST-segment elevation and ventricular tachycardia on Holter monitoring. Later, spasm occurred during a procainamide challenge performed for suspected Brugada syndrome. The patient underwent implantable cardioverter-defibrillator insertion and was successfully treated with oral calcium channel blocker.

DISCUSSION

We review contemporary data regarding management and outcomes in coronary vasospasm and discuss the use of implantable defibrillator therapy in patients who have sustained a significant arrhythmic event.
