Atrioventricular delay programming and the benefit of cardiac resynchronization therapy in MADIT-CRT.
The optimal atrioventricular pacing delay (AVD) in cardiac resynchronization therapy (CRT) remains to be determined. ⋯ Our findings indicate that in MADIT-CRT programming, the CRT AVD <120 ms was associated with a greater clinical and echocardiographic response to CRT.
