Abstract

Introduction: Brugada syndrome (BrS) is an inherited cardiac arrhythmia that strongly increases the risk of ventricular arrhythmia and sudden death. Vietnam belongs to the region with the highest frequency of BrS in the world. In our country, the clinical and subclinical symptoms of the disease have been described in small sizes, mainly in case-serie reports at several certain medical units. Objectives: To investigate the clinical and subclinical characteristics in BrS patients. Subjects and methods: A crossectional descriptive study in 117 BrS patients, investigated some clinical and subclinical characteristics, in hospitals in Ho Chi Minh City and Hanoi. The disease was diagnosed according to the European Heart Rhythm Society 2015 criteria. Results: There were 67,5% patients with no family history (most of the remaining having a sudden was under 45 years old); 53,0% were asymptomatic; 38,5% had syncope; 58,1% had no comorbidities; 73,5% were installed automated defibrillators. There were 70,9% with type 1 ECG; 9,4% were underwent a flecanide test (postive in 9/11 cases); 59,8% had an electrophysiologic study (postive in 55/70 cases).  Conclusion: The frequencies of some clinical and subclinical characteristics in BrS patients has been determined, similar to those published in the world.
