Incidence of Atrial and Ventricular Arrhythmias in Patients With Titin Truncating Variants Across the Ventricular Morphofunctional Phenotypic Spectrum.

BACKGROUND Titin truncating variants (TTNtvs), the most common genetic cause of dilated cardiomyopathy (DCM), are over-represented in early-onset atrial fibrillation (AF) and unexplained sudden cardiac arrest/death (SCA/SCD), suggesting they can cause arrhythmias before development of overt ventricular cardiomyopathy....
