In 38 patients with "pure" aortic stenosis, P terminal force in V(1)(V(1)Ptf) correlated well with left ventricular end-diastolic pressure (LVEDP) (n = 38, r =-0.59, p smaller than 0.001), Poorer, but nevertheless significant correlations were observed with aortic systolic pressure gradient (r = -0;32, p smaller than 0,05) and cardiac volume measured by X-ray (r = -0.34, p smaller than 0.05). No significant correlation was found between V(1)Ptf and peak systolic left ventricular pressure. If V(1)Pft more negative than -0.03 mm sec is used to detect elevated LVEDP (above 12 mm Hg), the sensitivity is 81 percent, and the specificity 86 percent. Increased left atrial volume is probably the most important mechanism of this relationship. V(1)Ptf is a useful tool for the assessment of the functional and hemodynamic state of the left ventircle in aortic stenosis.
在38例“单纯”主动脉瓣狭窄患者中，V1导联的P波终末电势（V1Ptf）与左心室舒张末期压力（LVEDP）密切相关（n = 38，r = -0.59，p < 0.001），与主动脉收缩压梯度（r = -0.32，p < 0.05）及X线测量的心脏容量（r = -0.34，p < 0.05）的相关性稍差，但仍具有显著性。未发现V1Ptf与左心室收缩压峰值之间存在显著相关性。若采用V1Ptf低于-0.03 mm·sec来检测升高的LVEDP（高于12 mmHg），其敏感性为81%，特异性为86%。左心房容量增加可能是这种关系的最重要机制。V1Ptf是评估主动脉瓣狭窄时左心室功能和血流动力学状态的有用工具。
