背景资料：右心导管检查（RHC）是诊断肺动脉高压（PH）的金标准，也是监测PH的有效工具，但由于RHC具有侵入性，常规使用RHC存在一些缺点。无创方法监测血流动力学需要管理PH患者。在这项研究中，我们的目的是评估的可靠性，无创血流动力学评估与全身阻抗心动图（无创心脏系统[NICaS]）为PH。方法和结果：我们调查了65例连续接受RHC。其中三分之二患有肺动脉高压，三分之一患有慢性血栓栓塞性PH; 25%的患者正在接受药物治疗。通过NICaS（NI-CO）、热稀释法（TD-CO）和Fick法（Fick-CO）估计心输出量（CO）。NI-CO与TD-CO呈显著正相关（r=0.715，P
Background: Right heart catheterization (RHC) is the gold standard for the diagnosis of pulmonary hypertension (PH) and a useful tool for monitoring PH. However, there are some disadvantages in the regular use of RHC because it is invasive. Noninvasive methods for monitoring hemodynamics are needed to manage patients with PH. In this study, we aimed to evaluate the reliability of noninvasive hemodynamic assessment with whole-body impedance cardiography (Non-Invasive Cardiac System [NICaS]) for PH.Methods and Results: We investigated 65 consecutive patients undergoing RHC. Two-thirds of them had pulmonary arterial hypertension and one-third had chronic thromboembolic PH; 25% of the patients were receiving medical therapy. Cardiac output (CO) was estimated by NICaS (NI-CO), thermodilution (TD-CO), and the Fick method (Fick-CO). There was a strong correlation between NI-CO and TD-CO (r=0.715, P
