title: Ventricular optimization of biventricular pacing: a systematic review.
abstract: Biventricular pacing has been shown to improve the overall clinical outcomes in patients with systolic heart failure and ventricular conduction delay on electrocardiogram. As correction of ventricular dyssynchrony is the putative mechanism of benefit, biventricular pacing is also termed as cardiac resynchronization therapy. The development of separate programmability of right and left ventricular output has led to a growing number of reports on the potential benefit of optimization of cardiac resynchronization by sequential biventricular pacing with different techniques and endpoints. This systematic review summarizes the current data for the optimization of sequential (V-V delay) compared with (default) simultaneous biventricular pacing in heart failure.
