Concomitant changes in ventricular depolarization and repolarization and long‐term outcomes of biventricular pacing

Biventricular (BiV) pacing increases transmural repolarization heterogeneity due to epicardial to endocardial conduction from the left ventricular (LV) lead. However, limited evidence is available on concomitant changes in ventricular depolarization and repolarization and long‐term outcomes of BiV pacing. Therefore, we investigated associations of BiV pacing‐induced concomitant changes in ventricular depolarization and repolarization with mortality (i.e., LV assist device, heart transplantation, or all‐cause mortality) and sustained ventricular arrhythmia endpoints.
