Brugada syndrome (BrS) is characterized by electrical abnormalities in the heart, and this study examines how signal-averaged electrocardiograms (SA-ECG) can evaluate late potentials (LP) for risk assessment in BrS patients.
The research involved 106 BrS patients, revealing that those with two or three abnormal LP criteria faced significantly higher risks of malignant arrhythmic events (MAEs), including sudden death.
The findings suggest that SA-ECG is a valuable noninvasive tool for identifying asymptomatic BrS patients at high risk for serious heart issues based on their LP characteristics.
