Implication
Supports EPS for risk stratification in Brugada syndrome; leaves open whether inducibility should guide ICD decisions.
Structured PICO
Does electrophysiologic study predict arrhythmic events in patients with Brugada syndrome?
P
Population
252 individuals with an ECG diagnostic of Brugada syndrome (coved-type ST segment elevation in precordial leads V1 to V3), including 116 symptomatic (syncope or aborted sudden cardiac death) and 136 asymptomatic patients.
I
Intervention
Electrophysiologic study (programmed ventricular stimulation)
O
Outcome
Arrhythmic events during follow-uphard clinical
Electrophysiologic testing provides prognostic value in Brugada syndrome, particularly for identifying low-risk asymptomatic patients who are noninducible.
