Abstract

We examined the effect of left ventricular filling on different combinations of programmable heart rate and atrioventricular delay in patients with dual-chamber pacemakers. Pacing mode with heart rates of 60 beats/min and 156 ms of atrioventricular delay induced a diastolic pattern that resembles more than others the one observed in healthy subjects in sinus rhythm.

摘要

我们研究了双腔起搏器患者中左心室充盈对不同可编程心率和房室延迟组合的影响。心率为60次/分钟且房室延迟为156毫秒的起搏模式所诱发的舒张模式比其他模式更类似于窦性心律的健康受试者中观察到的舒张模式。
