ECG changes at rest were noted in half of 87 patients with diabetes mellitus. Negative ECG changes in orthostatics were observed in 2/3 of the patients. The rate of the changes depends upon the heart rate increase, reflecting higher sympathetico-adrenal activity. The results of potassium salt application point to metabolic disorders in the myocardium of patients with diabetes mellitus. The orthostatic test performed during the course of treatment with potassium salt may serve as an index of efficiency and stability of the therapy conducted. ECG changes under physical exercise were observed in 14 of 54 patients, only in 4 of them the changes were tupical of coronary heart disease. Comparison of exercise tolerance, orthostatic and potassium salt tests which reveal cardiac damage of different nature, suggests that myocardial changes in patients with diabetes mellitus are mostly conditioned by the development of metabolic changes.
87例糖尿病患者中有一半在静息时出现心电图改变。2/3的患者在直立位时出现心电图阴性改变。这些改变的发生率取决于心率增加，反映了较高的交感-肾上腺活性。应用钾盐的结果表明糖尿病患者心肌存在代谢紊乱。在钾盐治疗过程中进行的直立位试验可作为所实施治疗效果和稳定性的指标。54例患者中有14例在体育锻炼时出现心电图改变，其中只有4例的改变为典型的冠心病改变。对揭示不同性质心脏损害的运动耐量、直立位和钾盐试验进行比较，提示糖尿病患者的心肌改变主要由代谢变化的发展所决定。
