Patients with Brugada syndrome who are asymptomatic and have no ventricular tachycardia/ventricular fibrillation inducibility by programmed electrical stimulation are at extremely low risk of experiencing late life-threatening arrhythmias. Methods Patients with BrS ( n  = 523; mean age, 51 ± 13 years; male, n  = 497) were enrolled.

Transcript of the video: Brugada Syndrome was described by Brugada brothers in 1992 as right bundle branch block pattern in anterior leads with ST segment elevation and syncope or sudden cardiac death and it was later in 1998, that the genetic basis of the disease was identified, with mutations in sodium channel.

Brugada syndrome is thought to account for about one fourth of sudden cardiac deaths in individuals with structurally normal heart. This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. Opinion is divided on the need for electrophysiology study.

A subgroup of patients with MVP may experience ventricular arrhythmias and sudden cardiac death (“arrhythmic mitral valve prolapse” [AMVP]) but how to stratify arrhythmic risk is still unclear. Abstract Introduction Mitral valve prolapse (MVP) is a common clinical condition in the general population.
