摘　　要：目的:探讨应用心阻抗法无创心功能检测仪监测充血性心力衰竭(CHF)时血流动力学变化,指导下一步治疗的应用价值。方法:入选67例CHF患者,应用无创心功能检测仪监测心率、基础阻抗、每搏输出量、心排血量、心缩力指数、收缩功能指数、舒张功能指数、外周血管阻力和血管顺应性指标,统计分析其用药前、用药后3 h和用药后3 d的患者的症状和以上指标的变化,分析无创心功能检测仪的应用价值。结果:用药前、用药后3 h和用药后3 d统计学分析显示心率和外周血管阻力下降,基础阻抗、每搏输出量、心排血量、心缩力指数、收缩功能指数、舒张功能指数和血管顺应性升高,有统计学差异((均P<0.01)。结论:无创心功能检测仪能反映CHF时血流动力学变化的过程,对CHF的治疗有一定的指导意义。AIM： To investigate the clinical value of noninvasive cardiac impedance detector in monitoring hemodynamic changes of congestive heart failure （CHF） for further treatment. METHODS： Noninvasive cardiac impedance detector was applied in 67 patients with CHF and indicators including heart rate, base impedance, stroke volume, cardiac output, cardiac contractility index, systolic function index, diastolic function index, total peripheral vascular resistance and blood vessel compliance were monitored. Changes of symptoms and the above indicators before and 3 h after treatment and on the third day after disease onset were recorded and analyzed. RESULTS： Statistical analysis showed that heart rate and total peripheral vascular resistance decreased, and base impedance, stroke volume, cardiac output, cardiac contractility index, systolic function index, diastolic function index, and blood vessel compliance indicators significantly increased before and after treatment. CONCLUSION： Noninvasive cardiac function detector can reflect hemodynamic changes in CHF and has some clinical value for the treatment of CHF.
