Cardiac arrhythmia

Julien Barc, Jean-Jacques Schott and Vincent Probst

 

The primary objective of our group is to improve healthcare by combining basic research and clinical activity into translational research programs. Taking advantage of large pedigrees and one of the largest worldwide cohorts of patients suffering from inherited cardiac electrical disorders (Brugada syndrome, the long and short QT syndrome, the catecholaminergic polymorphic ventricular tachycardia, conduction defects, sinus dysfunction, idiopathic ventricular fibrillation and arrhythmogenic cardiomyopathy) we apply multi-omics screening strategies to establish clinical and genetic risk stratification for developing cardiac arrhythmia and prevent sudden cardiac death (SCD). The identification of new clinical and molecular markers from these ‘sensitized’ models of SCD are likely relevant to the broad problem of SCD.
