Comparisons have been made on the vectorcardiogram, electrocardiogram and cardiac size of chest X-ray photograph between the healthy group and the patient groups with mitral stenosis and pulmonary emphysema, demonstrating the apparent difference of the effects of the right heart load. The possibility was suggested of making diagnosis and prescience of prognosis in chronic pulmonary emphysema based on the grade of right heart load. By analysis made on vectorcardiogram of 120 cases with chronic pulmonary emphysema, QRS loop was classified into three types in the horizontal plane and four types in the frontal plane. It is proved that the classification of QRS loop is useful for diagnosis and prognosis in the chronic pulmonary emphysema.
