Fever induced Brugada syndrome masquerading as STEMI

Abstract

Brugada Syndrome (BrS) is an autosomal dominant genetic disease determined by abnormal electrocardiographic (ECG) pattern and causes increased risk of sudden cardiac death. It is characterised by coved-type ST segment elevation in precordial leads V1-V3. There had been many proposed mechanisms explaining the link of sodium channel mutations and its electrophysiology. There are various triggering factors like fever, hypokalemia, ischemia, cocaine abuse and medications which unmask the ECG changes and these changes are usually transient. There is increased possibility of this cardiac rhythm to deteriorate into life threatening arrhythmias. Thus it is essential for the clinician to be aware of the conditions. We present such a scenario in which hyperthermia unmasked our patient’s Brugada syndrome.
