Arrhythmogenic Right Ventricular Dysplasia and Brugada Syndrome Overlap.

Arrhythmogenic right ventricular dysplasia (ARVD) and Brugada syndrome( BS) are associated with an increased risk of sudden cardiac death. Although they are described as two different entities, research suggests that they are not entirely separate. This paper presents a 55 years old male who presented for syncope. Interestingly, his electrocardiogram met the diagnostic criteria for both ARVD and BS. Subsequently, an implantable cardioverter-defibrillator (ICD) was implanted before discharge due to his high risk of sudden cardiac death. This case revealed that ARVD and BS clinical features can coexist in a single patient, and therefore supports the existence of a common pathophysiological basis of both diseases.
