为评价VVI型起搏器术后病人的心功能 ,用平衡法放射性核素心室造影测定 2 0例VVI型起搏器术后病人及 1 9例对照组的心功能。结果 :VVI起搏器组心室收缩功能参数LVEF、RVEF、LVPER、LV1 / 3EF、LV1 / 3ER与对照组比较无显著性差异 (P >0 .0 5 ) ,舒张功能参数LVPFR、LV1 / 3FF与对照组比较无显著性差异 (P >0 .0 5 ) ,而LV1 / 3FR与对照组比较有显著性差异 (P <0 .0 5 ) ,心室收缩协调性参数PS和LVPHSD与对照组比较有非常显著性差异 (P <0 .0 1 )。提示 :VVI型起搏器使心室收缩协调性下降 ,但对心功能无显著影响 ,有一定临床应用价值。
To evaluate the cardiac function of postoperative patients with VVI pacemaker, the cardiac function of 20 patients with VVI pacemaker and 19 controls were measured by radionuclide ventriculography. Results: There was no significant difference in LV ventricular systolic function parameters LVEF, LVVE, LV1 / 3EF and LV1 / 3ER between VVI group and control group (P> 0.05). LVPFR, LV1 / 3FF and There was no significant difference between the control group and the control group (P> 0.05), while the LV1 / 3FR was significantly different from the control group (P <0.05). The ventricular systolic parameters PS and LVPHSD compared with the control group Very significant difference (P <0.01). Tip: VVI pacemaker to reduce the coordination of ventricular contraction, but no significant effect on cardiac function, there is a certain clinical value.
