摘要:
作者对23例安装永久性起搏器患者, 采用二维超声, 比较起搏器植入前后血流动力学的变化。结果显示: 植入后心房按需起搏(AAI) 组和心室按需起搏(VVI) 组的心排血量均明显增加(P<0.05) , 分别增加40.6% 和12%; 但植入后VVI组的左室射血分数、每搏量、左室舒张末期容积均降低(P<0.05) ,AAI组无变化。研究表明AAI生理性起搏对于患者血流动力学的改善优于VVI非生理性起搏。心排血量是评价血流动力学改善的敏感指标。
Abstract:
Two-dimension echocardiography was used to evaluate the hemodynamic consequences in 23 patients with implanted permanent cardiac pacemakers.The results showed in both AAI and VVI pacing system groups, the cardiac output was increased 40.6% and21.2% , respectively. In VVI group , left ventricular (LV) ejection fraction and stroke volume and LV enddiastolic volume were decreased, but in the AAI group they were not changed. The study suggested AAI with the characteristic of physiologic pacing is preferable to VVI non-physiologic pacing in hemodynamic benefit. The cardiac output is a sensitive parameter in evaluation of hemodynamic changes of cardiac pacing.
