Impedance cardiography: more questions than answers.

摘要: Thoracic electrical bioimpedance, also known as impedance cardiography (ICG), is a noninvasive method to obtain hemodynamic measurements, including cardiac output. Recently, there has been flurry of reports on the clinical use ICG. Authors have suggested that ICG measurements are useful for myriad situations, diagnosis heart failure, monitoring patient’s status, and assisting in medicine titration decisions. However, data continue suggest poor correlation between current generation devices invasive output, especially failure patients. not able accurately measure left ventricular filling pressures. There limited demonstrating any improved outcomes using setting. Given available data, should be research
