To study the P terminal index a method of additionally fortified ECG (I mV-50 mm) has been used permitting more precise assessment of the low amplitude elements of the ECG curve. The values of P terminal index in the lead V1 ECG in the healthy individuals and the limits of its changes in the patients with ischaemic heart disease have been determined. The comparison of the parameters of the P terminal index in the lead V1 ECG and the degree of insufficiency of the left ventricle confirms the link between the increase of this index and the presence of congestion in the lungs.
为研究P波终末指数，采用了一种增强型心电图方法（1 mV - 50 mm），可更精确地评估心电图曲线的低振幅成分。已确定了健康个体V1导联心电图中P波终末指数的值及其在缺血性心脏病患者中的变化范围。比较V1导联心电图中P波终末指数参数与左心室功能不全程度，证实了该指数升高与肺部充血之间的联系。
