In 100 patients with chronic ischaemic heart disease and diffuse changes in the myocardium the data of 12 common ECG leads indicated that the corrected orthogonal leads according to Mac Fee--Parungao and Frank reflect these changes in all cases. The severity of the diffuse changes reflected in the deviations of the ST segment and the T-wave in the orthogonal leads corresponds to that reflected in the 12 common leads. A mathematical analysis of the waves of the QRS complex in the X, Y and Z leads indicates a growth of the left ventricular potentials with the development of diffuse myocardial changes. The mentioned systems of orthogonal leads can be recommended for wide employment for the diagnosis of diffuse changes in the myocardium in ischaemic heart disease.
在100例患有慢性缺血性心脏病且心肌有弥漫性改变的患者中，12个常规心电图导联的数据表明，根据麦克菲 - 帕伦高和弗兰克法校正的正交导联在所有病例中均能反映这些改变。正交导联中ST段和T波偏移所反映的弥漫性改变的严重程度与12个常规导联所反映的一致。对X、Y和Z导联中QRS波群进行数学分析表明，随着弥漫性心肌改变的发展，左心室电位增强。上述正交导联系统可推荐广泛用于诊断缺血性心脏病中的心肌弥漫性改变。
