背景-多普勒超声心动图目前用于评估心血管疾病患者的左心室和右心室血流动力学。然而，关于其在不稳定失代偿性心力衰竭患者中的准确性，存在相互矛盾的报道。本研究的目的是评估该技术在不稳定心力衰竭患者中的准确性。方法和结果-连续失代偿性心力衰竭患者通过有创和多普勒超声心动图同时评估左心室和右心室血流动力学。在 79 名患者中，无创测量每搏输出量（r=0.83，P
Background-Doppler echocardiography is currently applied for the assessment of left ventricular and right ventricular hemodynamics in patients with cardiovascular disease. However, there are conflicting reports about its accuracy in patients with unstable decompensated heart failure. The objective of this study was to evaluate the accuracy of the technique in patients with unstable heart failure.Methods and Results-Consecutive patients with decompensated heart failure had simultaneous assessment of left ventricular and right ventricular hemodynamics invasively and by Doppler echocardiography. In 79 patients, the noninvasive measurements of stroke volume (r=0.83, P
