title: Coronary blood flow velocity during apical versus septal pacing.
abstract: Previous studies have indicated that ventricular asynchrony may significantly affect resting coronary blood flow velocity. Our study argues against this hypothesis, as comparable left anterior descending blood flow velocities were found during three pacing modalities, associated with varying degrees of asynchrony: (a) atrial pacing, (b) atrioventricular (AV) sequential pacing from the right ventricular apex and (c) AV sequential pacing from the proximal right ventricular septum.
