3) Right ventricular apical pacing
右室心尖部起搏
1.
Objective To find a forecasting index of left cardiac structure and function in patients with right ventricular apical pacing.
目的探讨右室心尖部起搏QRS波时限在左室结构及功能评价中的价值。
4) right ventricular apex pacing
右室心尖部起搏
1.
Objective:To compare the cardiac function impact by right ventricular septum pacing and right ventricular apex pacing.
目的:对比右室心尖部起搏与右室间隔部起搏对心功能的影响。
5) right ventricular outflow tract pacing
右室流出道起搏
1.
Objective: The aim of our study was to compare cardiac output (CO) during short-term atrioventricular sequential pacing from the right ventricular apex and from the outflow tract of the right ventricle, to assess if short-term right ventricular outflow tract pacing were much better than right ventricular apical pacing.
目的:在房室顺序起搏下,比较右心耳、右室心尖部和右室流出道起搏时心输出量(CO)的变化,明确右室流出道起搏是否优于右室心尖部起搏。
2.
Background:As proved by more and more clinical and experimental researches, right ventricular pacing for long time inducing LBBB may cause hemodynamic disorder and systolic dys-synchrony of LV,which drives people to find new alternative pacing site-right ventricular outflow tract pacing.
研究背景由于越来越多的临床和基础研究的证据表明:长期右室心尖部起搏可能引起类似与医源性左束支传导阻滞的改变,随之而出现左室血流动力学紊乱和左室不同步收缩,继而寻找新的起搏位点—右室流出道起搏,但是目前并无明确定论右室流出道起搏优于传统的右室心尖部起搏。
6) Rapid ventricular pacing
快速右室起搏
1.
Methods Twelve dogs were subjected to rapid ventricular pacing after ligation of the left anterior descending coronary artery (LAD), to induce the cardiac output (CO) to reduce by 25% and 50% from the basal level.
方法完全结扎犬前降支和进行快速右室起搏,使心输出量(CO)较基础状态稳定地下降25%和50%,分别测定基础及心输出量下降状态下的血压(AP)、血氧(SaO2)、平均右房压(mRAP)、平均肺毛压(mPCWP)、系统血管阻力(SVR)值并以超声心动图测定心腔大小和左室射血分数(LVEF)。
