摘　　要：房室间期在双腔起搏器患者中具有重要意义,不仅对心房收缩及心室充盈产生影响,且与右心室起搏比例有关联,给心脏血液动力学及心功能带来一系列影响,合适的房室间期,才能使双腔起搏器患者心脏血液动力学及心功能获益更多。Atrioventricular delay（AVD）is of great importance in dual-chamber pacemakers. It may not only effect atrial systolic and ventricle diastolic, but also have association with cumulative percent ventricular paced （Cum%VP）. It may also produce a series of effect on cardiachemodynamics and function. Only the AVD optimization may bring the most benefits for cardiac hemodynamics and function of patients with dual-chamber pacemakers.
