The purpose of this paper is to review our experience with impedance cardiography when used to evaluate cardiovascular control mechanisms in humans. We used the Minnesota impedance cardiograph and the Kubicek stroke volume formula, modified by using spot electrodes instead of band electrodes, a constant rho of 135, and careful attention to standardized procedures. With this technique we focused on the changes in cardiovascular variables with postural stress and during the Valsalva maneuver. More complete definition of cardiovascular function can be obtained by the use of this technique. We describe novel cardiovascular data with the use of impedance cardiography in humans.
本文的目的是回顾我们使用阻抗心动描记术评估人类心血管控制机制的经验。我们使用了明尼苏达阻抗心动描记仪和库比克每搏输出量公式，通过使用点状电极而非带状电极、恒定的电阻率135以及严格遵循标准化程序对公式进行了修正。通过这项技术，我们重点研究了姿势应激和瓦尔萨尔瓦动作期间心血管变量的变化。使用这项技术能够更全面地定义心血管功能。我们描述了使用阻抗心动描记术获得的关于人类的新的心血管数据。
