Early electrocardiographic diagnosis of chronic cor pulmonale was attempted in the study of 312 patients with chronic pneumonia and in 251 normal individuals. In comparing the mean values of several ECG indices in chronic pneumonia, Stage 1, some signs with significant differences were revealed (amplitude of the PaVF wave, ratio of the hight of the PII and TII Waves, are of the PII wave). These signs appeared to be most informative. The following groups were singled out: 38 patients with chronic pneumonia, Stages 1 and 2 with signs of bronchospasm, and 53 persons with the same stages of the disease, but free of bronchial patency disorders. The ECG of these groups of patients was evaluated by means of the tables of electrocardiographic diagnosis of right atrial hypertrophy. The signs of overloading of the right atrium were revealed with statistical significance more often in patients with bronchospasm. The possibility of using this table for revealing early electrocardiographic signs of chronic cor pulmonale was also established; these signs include the amplitude of the PII wave greater than 2 mm and PaVF 1.5 mm, ratio of the hight of the PII and TII waves less than 0.75, the are of the PII wave greater than 0.09.
在对312例慢性肺炎患者和251名正常个体的研究中，尝试对慢性肺源性心脏病进行早期心电图诊断。在比较慢性肺炎1期患者的几个心电图指标的平均值时，发现了一些有显著差异的体征（PaVF波振幅、PII波和TII波高度比、PII波面积）。这些体征似乎最具信息量。挑选出以下几组：38例1期和2期慢性肺炎且有支气管痉挛体征的患者，以及53例处于相同疾病阶段但无支气管通畅障碍的患者。通过右心房肥大心电图诊断表对这些患者组的心电图进行评估。支气管痉挛患者右心房超负荷体征的检出具有统计学意义的情况更为常见。还确定了使用该表揭示慢性肺源性心脏病早期心电图体征的可能性；这些体征包括PII波振幅大于2mm、PaVF波振幅大于1.5mm、PII波和TII波高度比小于0.75、PII波面积大于0.09。
