Do specific ECG markers predict arrhythmic events in patients with Brugada syndrome?
Do specific ECG markers predict arrhythmic events in patients with Brugada syndrome?
A spontaneous type 1 ECG pattern and other specific depolarization/repolarization markers are associated with increased arrhythmic risk in Brugada syndrome.
Spontaneous type 1 ECG remains central to BrS risk stratification; additional markers are hypothesis-generating and should not yet change practice.
Several clinical, electrocardiographic (ECG) and electrophysiological markers have been proposed to provide optimal risk stratification in patients with Brugada syndrome (BrS). Of the different markers, only a spontaneous type 1 ECG pattern has clearly shown a sufficiently high predictive value. This review article highlights specific ECG markers based on depolarization and/or repolarization that have been associated with an increased risk of arrhythmic events in patients with BrS.
