A Case of Asymptomatic Brugada Electrocardiographic Pattern Incidentally Unmasked During the Recovery Phase of an Exercise Stress Test
Keywords:Brugada syndrome, Brugada ECG pattern, Exercise stress test, channelopathies, sudden cardiac death
The interest about Brugada syndrome, an inherited channelopathy associated with sudden cardiac death in individuals without structural heart disease, is exponentially increasing lately. Similarly to chameleon, the electrocardiographic (ECG) signal of the disease fluctuates over time, it is often concealed, and may be unmasked under certain conditions. Recently, emergence of the characteristic ST-segment elevation during exercise stress test (EST) has been reported, probably resulting from an alteration of the autonomic tone in the different stages of exercise. We present the case of a 43-year-old, otherwise healthy male with an asymptomatic Brugada ECG pattern incidentally unmasked during the recovery phase of an EST.
