SmartDelay Determined AV Optimization: A Comparison to Other AV Delay Methods Used in Cardiac Resynchronization Therapy - SMART-AV


The goal of the trial was to compare optimization of atrioventricular (AV) delay by echocardiography versus an electrocardiogram (ECG)-based algorithm (SmartDelay) versus a fixed interval of 120 ms among patients who received cardiac resynchronization therapy (CRT).
