It is now possible to diagnose early cor pulmonale by utilizing electrocardiographic fluctuations which are the result of moderate pulmonary hypertension and the accompanying effect upon right ventricular function. This holds whether the ECG alterations are produced by chronic obstructive pulmonary disease or by the rarer forms of obliterative lung disease. The late stage of cor pulmonale, in which right ventricular hypertrophy is manifest, should now be rarely encountered in view of our improved understanding of cor pulmonale and more rational therapeutic approaches to the underlying disorders.
现在，利用心电图波动来诊断早期肺心病成为可能，这些波动是中度肺动脉高压及其对右心室功能的伴随影响的结果。无论心电图改变是由慢性阻塞性肺疾病还是由较罕见的闭塞性肺疾病引起，都是如此。鉴于我们对肺心病有了更好的理解以及对潜在疾病采取了更合理的治疗方法，现在很少会遇到右心室肥大明显的晚期肺心病。
