没有左心室容量超负荷、明显心律失常或明显心包积液的患者[66]在诊断性左心和右心导管插入术之前立即通过M型超声心动图进行检查。使用各种超声心动图测量，根据先前提出的 8 种不同超声心动图公式 (SVE) 计算左心室每搏输出量 (SV)。导管插入时，还通过热稀释 (SVT) 和右前斜投影 (SVA) 中的单平面左心室电影血管造影来确定 SV。将 SVE 与 SVT 进行比较时，用于计算二尖瓣或主动脉流量的 4 个公式失败了（r [相关系数] = 0.10 至 0.54）。当用于根据心室直径计算心室容积或根据直径变化计算 SV 的公式（左心室公式）用于心室收缩模式严重不对称的冠心病患者时，发现相关性较差（r = 0.22-0.47）。当左心室公式的使用仅限于对称或几乎对称收缩的患者时，2个公式产生了良好的相关性，分别为r = 0.84，SEE [估计的标准误差] = 12.7 ml和r = 0.86，SEE = 12.2 ml。这些相关性与 2 种侵入性参考技术之间的相关性相当（r = 0.81；SEE = 12.2 ml）。 SVE 和 SVA 之间的比较证实了热稀释研究的结果，尽管相关性普遍较弱。 Teichholz 等人的公式是所有测试公式中最好的，可用于在可预期出现对称或几乎对称左心室收缩的患者中获得临床上有用的 SV 估计。
Patients [66] without left ventricular volume overload, significant arrhythmia or significant pericardial effusion were examined by M-mode echocardiography immediately before diagnostic left- and right-heart catheterization. Using various echocardiographic measurements, left ventricular stroke volume (SV) was calculated according to 8 different echocardiographic formulas (SVE) previously proposed. At catheterization SV was also determined by thermodilution (SVT) and by single-plane left ventricular cineangiography in the right anterior oblique projection (SVA). When comparing SVE to SVT, the 4 formulas developed to calculate mitral or aortic flow failed (r [correlation coefficient] = 0.10 to 0.54). Poor correlations (r = 0.22-0.47) were found when formulas used to calculate ventricular volumes from the ventricular diameter or SV from the change in diameter (left ventricular formulas) were used in coronary patients with grossly asymmetrical ventricular contraction patterns. When the use of the left ventricular formulas was confined to patients with symmetrical or almost symmetrical contraction, 2 formulas yielded favorable correlations of r = 0.84, SEE [standard error of the estimate] = 12.7 ml and r = 0.86, SEE = 12.2 ml, respectively. These correlations were comparable to the correlation between the 2 invasive reference techniques (r = 0.81; SEE = 12.2 ml). The comparison between SVE and SVA confirmed the results of the thermodilution study, though the correlations were generally weaker. The formula of Teichholz et al., which was the best of all tested formulas, may be used to obtain a clinically useful estimate of SV in patients in whom symmetrical or almost symmetrical left ventricular contraction can be anticipated.
