The authors compared the electrical activity of the heart with results of echocardiography during rest and during bicycle ergometry [correction of veloergometry] in 240 patients with ischemic heart disease, 60 patients with hypertensive disease and in 16 healthy persons. In some of the patients coronarography was carried out. It was established that the informative value of electrocardiography in assessment of the anatomo-functional state of the left ventricle depended on the contingent of the examined patients and reduces as disorders of the functional state of the myocardium tended to advance. The specificity and sensitivity of the electrocardiographic signs of left ventricular hypertrophy reduced in disturbances of ventricular conduction, presence of myocardial infarction in the anamnesis, increase of involvement of the cardiac arteries.
作者比较了240例缺血性心脏病患者、60例高血压病患者以及16名健康人的静息状态和进行自行车测力计运动[将veloergometry改为正确表述]期间心脏的电活动与超声心动图结果。部分患者进行了冠状动脉造影。结果表明，心电图在评估左心室解剖功能状态方面的信息价值取决于受检患者群体，并且随着心肌功能状态紊乱趋于严重而降低。左心室肥厚心电图征象的特异性和敏感性在心室传导障碍、既往有心肌梗死病史、冠状动脉受累程度增加时降低。
