Cardiac output figures from 97 patients were computed by earpiece densitometry and correlated to various dimensional parameters. Stroke volume was better correlated to body dimensions than cardiac output indicating that patients undergoing right heart catheterization were not in basal state.
通过听筒密度测定法计算了97例患者的心输出量,并将其与各种维度参数相关联。与心输出量相比,每搏输出量与身体维度的相关性更好,这表明接受右心导管检查的患者并非处于基础状态。
