title: [Characteristics of the U wave on the electrocardiogram of patients with diabetes mellitus type 1 without clinical signs of cardiac damage].
abstract: Additionally increased (1 mB = 50 mm) ECG recorded in 137 patients with diabetes mellitus without clinical signs of cardiac damage and 66 healthy subjects revealed that the incidence of positive U wave was less in the patients than in the healthy subjects. The negative U wave was found in leads aVR, III, aVL, and V1 in healthy subjects. In patients with diabetes mellitus, the negative and diphasic U waves were found in all the ECG leads. The amplitude of a positive U wave on a ECG strip of the patients was significantly lower in leads V1 and V2 than that of the healthy subjects. The findings are regarded as manifestations of metabolic and dystrophic myocardial changes of diabetic origin.
