Exercise stress test unmasking a Brugada pattern in a survivor of cardiac arrest: a case report

In BrS, VA most commonly occur at rest, during sleep, or during exercise recovery, when vagal tone is predominant. This case demonstrates that BrS Type 1 ECG changes may also be elicited during peak sympathetic stimulation, such as intense exercise. This rare presentation suggests that exercise stress testing could play a role in the diagnostic and risk stratification process in selected patients with suspected BrS. Furthermore, it raises questions regarding the safety of physical activity in this population and whether current recommendations on sports participation warrant re-evaluation in light of such findings.
