Why the study?
Do specific 12-lead ECG and electrophysiological parameters predict the development of atrial tachyarrhythmias in subjects with type 1 ECG pattern of Brugada syndrome?
Do specific 12-lead ECG and electrophysiological parameters predict the development of atrial tachyarrhythmias in subjects with type 1 ECG pattern of Brugada syndrome?
Simple 12-lead ECG and electrophysiological parameters, particularly an HV interval >= 56 ms, can identify patients with Brugada syndrome at high risk for developing atrial tachyarrhythmias.
No takes yet. Share an insight, caveat, or question.
HV interval >=56 ms was associated with AT risk in Brugada syndrome; supports hypothesis-generating stratification but requires prospective validation.
Letsas et al. (2009) studied this question.
