A statistically highly significant correlation exists between the values of left ventricular end-diastolic pressure and the dimensions of the terminal segment of the P wave in the electrocardiographic V 1 lead. Values lower than -0.03 mmsec were found only in patients with pathologically elevated left ventricular end-diastolic pressure. In a group of 94 patients with acute transmural myocardial infarction, pathologically low values were found in 43% of the patients on the first day of the disease; on the fifth day of disease the frequency of pathological values of PTF---V 1 sank statistically significantly. A gradual decrease in the values of PTF---V 1 is a sign of bad prognosis in patients with acute myocardial infarction. Changes in the terminal segment of the P wave, at preserved sinus rhythm, can be read off any electrocardiographic curve. Their evaluation offers valuable information about changes in left ventricular end-diastolic pressure, when facilities for catheterization of the patient are not available. This possibility constitutes the main practical value of the method described.
左心室舒张末期压力值与心电图V1导联P波终末段的幅度之间存在统计学上高度显著的相关性。仅在左心室舒张末期压力病理性升高的患者中发现低于-0.03毫米秒的值。在一组94例急性透壁性心肌梗死患者中，43%的患者在疾病第一天出现病理性低值；在疾病第五天，PTF-V1病理性值的频率在统计学上显著下降。PTF-V1值逐渐降低是急性心肌梗死患者预后不良的标志。在窦性心律保持不变的情况下，P波终末段的变化可以从任何心电图曲线上读出。当没有患者导管插入术设备时，对其评估可提供有关左心室舒张末期压力变化的有价值信息。这种可能性构成了所述方法的主要实际价值。
