A comparison of the values of R-R, S1S2, QS1, QS2, LVET, PEP, and ICT recorded from the carotid pulse of 40 coronary patients and 40 normal subjects has shown that the coronary group, when compared with the normals, show: --A significant lengthening of the QS2, PEP and ICT values, and a tendency towards lengthening of the S1S2 interval. --A tendency towards shortening of the LVET period. The ratio of PEP/LVET is a particularly good discriminant factor between the two groups. Because of these differences, assessment of the carotid pulse, which is an easy and non-invasive investigation, has become a good means of diagnosing coronary arterial disease. The results of this study have been compared with those from previous studies, and the clinical significance of the different findings has been analysed.
对40名冠心病患者和40名正常受试者颈动脉搏动记录的R-R、S1S2、QS1、QS2、左室射血时间（LVET）、射血前期（PEP）和等容收缩时间（ICT）值进行比较，结果显示，与正常组相比，冠心病组呈现：——QS2、PEP和ICT值显著延长，S1S2间期有延长趋势。——左室射血时间（LVET）有缩短趋势。PEP/LVET比值是两组间特别好的鉴别因素。由于这些差异，颈动脉搏动评估作为一种简便且无创的检查方法，已成为诊断冠状动脉疾病的良好手段。本研究结果已与先前研究结果进行比较，并分析了不同发现的临床意义。
