摘　　要：目的体外反搏治疗新装置CN3的充排气工作模式和动力系统比旧装置CN2有了较大的改进,为此对比观察CN3与CN2的反搏指脉波变化和效果。方法冠心病患者45例,分别采用CN3与CN2治疗1h,分别测定指脉波的D/S(舒张波/收缩波)的波峰比值和面积比值。结果CN3组、CN2组的波峰比值分别是1.77±0.39、1.52±0.19,CN3组高于CN2组(P<0.01);CN3组、CN2组的面积比值分别是2.25±0.64、1.64±0.22,CN3组高于CN2组(P<0.01)。结论CN3提高指脉波峰值和面积,其反搏效应优于CN2。Objective Model CN3 of external counterpulsation device has been modified on its air driving and working pattern. The present study was designed to compare the effect of finger plethosmography between model CN2 and CN3.Methods Fort-five patients with coronary artery disease undertook the treatment of EECP by CN3 or CN2 for an hour. The amplitude and area ratios of their D/S (diastolic waveform/systolic waveform) of finger plethysmogram resulted in the two devices are measured respectively.Results The amplit...
