[Method of using Sokolow's and Lyon's electrocardiographic signs for the diagnosis of chronic cor pulmonale]

A method introduced by the authors for the diagnosis of chronic cor pulmonale based on the evaluation of Sokolov's and Lion's electrocardiographic criteria is described. The results presented were checked by comparing the pathoanatomic data of 124 patients dying of chronic pulmonary lesions, as well as the analysis data of ECG recorded in 92 normal individuals with a vertical or semi-vertical electric position of the heart. The advantages of the suggested method over that of Widimski are indicated.
