摘　　要：目的观察具有心室自动夺获功能(AC)的双腔起搏器(Kappa700)置入后参数的变化情况和安全性。方法随访56例置入Kappa700型起搏器患者,观察术后1周及术后1、3、6个月心室起搏阈值、输出电压等参数的变化。结果56例患者于术后1周打开心室自动夺获功能,心室起搏阈值在术后1周达到最大值,由植入时的(0.40±0.05)V升至(0.75±0.22)V,1～6个月后逐渐下降稳定于(0.61±0.31)V。心室起搏输出电压也随之升高而后逐渐下降稳定于(1.22±0.42)V,明显低于普通起搏器的输出电压(2.5～4.5V)。该起搏器由于具有电压4.5V,脉宽0.49ms的备用脉冲,保证了当心室失夺获时起搏的安全性。结论具有AC功能的Kappa700型双腔起搏器输出能耗低、安全可靠。Objective To observe the changing parameter and safty of dule chamber Pacemaker with ventricular autocapture function. Methods Ventricular stimulater threshold, ventricular output amplitude and so on were measured in fifty-six patients implanted Medtronic Kappar 700 pacemaker at 1 th week, 1 th month, 3th month,6 th month after implantation. Results The ventricular pacing threshold increased to the highest at 1 th week, from （0.40 ± 0.05） V to （0.75 ± 0.22） V, decreased to （1.22 ± 0.42） V after lth - 6th month, ventriculer output amplitude also increased, and dcreased slowly to （ 1.22 ± 0. 42） V, that is lower than the Dule chamber Pacemaker without autocapture function. Kappar 700 pacemaker is safty with backup （ amplitude4. 5V,pulse width0. 49 ms） pulse when the ventricular is not captured. Conclusion The result suggest that the dule chamber pacemaker with autocapture function could safly work with lower output amplitude.
