摘　　要：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 ventricular function of patients after VVI pacing, 20 patients after VVI pacing and 19 controls were studied by gated cardiac blood pool imaging. There was no significant difference in the parameters of systolic function (LVEF?RVEF?LVPER?LV1/3EF?LV1/3ER) between VVI group and control group( P >0.05). There was no difference in the parameters of diastolic function (LVPFR?LV1/3FF) between the two groups either( P >0.05). LV1/3FR of the VVI group was significantly higher than that in the control group( P <0.05). The parameters of left ventricular systolic coordination (PS and LVPHSD) were significantly lower after VVI pacing than the control group( P <0.01). The results suggest that the left ventricular systolic coordination of patients after VVI pacing is lower and ventricular function remains stable.
