Abstract 13007: Change in QRS 3D Voltage Time Integral (3D QRS Area) Predicts Left Ventricular Reverse Remodeling in Sacubitril-Valsartan Treated Patients With Left Bundle Branch Block

Introduction: The instantaneous absolute 3D ECG voltage integrated over the duration of QRS (VTIQRS-3D) is an improved marker of left ventricular (LV) electrical dyssynchrony compared to QRS durati...
