Features of bioelectrical activity of the heart in children with chronic pyelonephritis

The objective was to determine the characteristics of the bioelectrical activity of the heart in children depending on the duration of chronic pyelonephritis and concomitant chronic foci of infection. Analysis of elecrocardiographic research results of 269 children with chronic pyelonephritis at the age from 1 to 17 years was done. Depending on pyelonephritis duration children were divided into 3 groups: up to 3 years, 3 to 6 years, 6 years and more. Violation of repolarization in the ventricular myocardium were detected more frequently in children with chronic pyelonephritis combined with chronic foci of infection in the nasopharynx. If the duration of chronic pyelonephritis was than three years, violations of repolarization in the ventricular myocardium were revealed almost in every child. These features of bioelectrical activity of the heart in children with chronic pyelonephritis testify to the need in treatment and prevention of the underlying disease, in the rehabilitation of chronic foci of infection to prevent progression of disorders of the functional state of cardio - vascular system.
