Impedance cardiography technology, along with recent advances in the impedance cardiography (ICG) device, has become a provocative but not yet proven noninvasive alternative to invasive hemodynamic measurements. The results from stroke volume and cardiac output measurements by ICG show reasonably accurate correlation to the values calculated from direct measurements from pulmonary artery catheters. ICG may be a useful adjunct to clinical judgment for heart failure patients. The available data would not yet support supplanting invasive hemodynamic assessment in the critical care setting with ICG. Future studies and advances in technology are expected to improve impedance cardiography, thus broadening its clinical applications. Ongoing research must confirm the precise benefits of this information for ICG monitoring to become a standard assessment in heart failure.
随着阻抗心动图（ICG）设备的最新进展，阻抗心动图技术已成为一种具有启发性但尚未得到证实的侵入性血流动力学测量的非侵入性替代方法。通过ICG测量每搏输出量和心输出量的结果与通过肺动脉导管直接测量计算出的值显示出合理准确的相关性。ICG可能是心力衰竭患者临床判断的有用辅助手段。现有数据尚不支持在重症监护环境中用ICG取代侵入性血流动力学评估。预计未来的研究和技术进步将改善阻抗心动图，从而扩大其临床应用。正在进行的研究必须确认ICG监测这些信息的确切益处，以便使其成为心力衰竭的标准评估方法。
