BACKGROUND

Brugada syndrome is an inheritable syndrome that carries an increased risk of sudden cardiac death. This study aims to delineate the natural history, clinical and electrophysiologic profile, treatment strategies, and outcomes of patients with Brugada pattern electrocardiogram (ECG) and Brugada syndrome in a tertiary care hospital in the Philippines.

METHODOLOGY

This is a retrospective observational study of patients diagnosed with Brugada pattern ECG and Brugada syndrome admitted in a single center from 2004 to 2019.

RESULTS

Twenty-three patients were included in the study. All patients were male. In both groups, the majority were nonsmokers (n = 13) and nonalcoholic beverage drinker (n = 14). In patients with Brugada pattern ECG, all presented as an incidental finding (n = 10; P < 0.001), whereas in Brugada syndrome, six patients presented with out-of-hospital resuscitated cardiac arrest (46.15%, P = 0.019). There were only three patients with a family history of sudden cardiac death. All patients had normal ejection fraction and sinus rhythm. Twenty-one patients had ST elevation (91.30%). Fourteen patients had spontaneous type 1 Brugada pattern ECG, whereas the rest were inducible to type 1 after flecainide test. Seven patients underwent implantable cardioverter defibrillator implantation before discharge; one patient died at the time of diagnosis, and one had recurrent admission for arrhythmia. No single patient received medical management.

CONCLUSION

Clinical profile, ECG findings, and outcomes were not significantly different between the two groups of patients except for the clinical presentation upon diagnosis. Treatment strategies were guideline-directed.
