摘要
目的 观察安置心脏永久起搏器前后心功能的变化。 方法 安置 VVI型埋藏式永久性心脏起搏器后 90天左右行超声心动图检查 ,测量心脏每搏量 ( SV)、射血分数 ( EF)、心输出量 ( CO)、心脏指数 ( CI) ,99m Tc-核素平衡法门控心血池显像测定左室射血分数 ( GEF)、峰射血率 ( PER)、峰充盈率 ( PFR)及心室相角程 ( DPH)。 结果 超声心动图示起搏器安置后 ,CO增加 17.3% ( P<0 .0 5 ) ,CI增加 2 3.5 % ( P<0 .0 5 )。SV、EF及呈下降趋势 ,但差异无显著性。心血池检查显示起搏器安置后 PER降低 40 .8% ( P<0 .0 5 )。GEF、PFR减小 ,DPH增大 ,差别亦无显著性。 结论 安置 VVI型心脏永久起搏器后心输出量和心脏指数显著增加 ,心脏收缩功能和舒张功能均呈下降趋势。
To explore the change of cardiac function pre and after installing the permanent pacemaker. \ Methods\ Compared the change of GEF,PER,PFR and DPH by \+\{99m\}Tc gate control blood pool scinitigraphy and the change of SV,EF,CO,CI by echocardiogram before and after installing the permanent pacemaker in 90 days. \ Results\ Blood pool scinitigraphy revealed that PER decreased 40.8%(P<0.05).\ GEF, PFR decreased, DPH increased, but there were no statistical significance. \ Echocardiogram revealed that CO, CI increased 17.3%, 23.5%, respectively. \ SV,EF decreased, but there was no statistical significance. \ Conclusions\ The CO, CI increased significantly after the installation of permanent pacemaker. \ Otherwise the systolic and diastolic function decreased, the cause of which was the increasing of the heart rate. \ So the hemodynamics of the patients and the perfusion of the tissue were ameliorated, the life quality was improved.\;
