临床研究证实双腔起搏器的右室心尖部高比例起搏会导致心室电机械活动失同步,增加患者心衰和房颤的发生风险。而双腔起搏器最小化心室起搏功能的应用,通过特定的起搏模式,可以在保证安全的基础上尽可能减少不必要的右心室起搏,让更多的室上性激动沿自身房室传导系统下传,最大程度地改善患者的血流动力学效应。本文就最小化心室起搏功能的产生背景、常用模式和临床研究进展等问题作一综述。
Clinical studies have confirmed that double-chamber pacemaker pacing right ventricular apical high ratio will lead to ventricular electrical mechanical synchronization loss, increase the risk of heart failure and atrial fibrillation. The dual-chamber pacemaker to minimize ventricular pacing function of the application, through a specific pacing mode, you can be on the basis of ensuring safety to minimize unnecessary right ventricular pacing, so that more of the supraventricular activation along its own Atrioventricular conduction system to download, to maximize the patient’s hemodynamic effects. This article reviews the background, common patterns and progress of clinical studies to minimize ventricular pacing.
