title: [Electrocardiographic changes in patients with chronic kidney failure treated by periodic hemodialysis].
abstract: The data from the analysis of 254 electrocardiograms of 110 patients with chronic renal insufficiency, treated with periodic hemodialysis are presented. The most often electrocardiographic change is the protraction of electric systole of the heart (interval QT). It is observed in 70% of the patients. Second comes the left ventricular hypertrophy with 33.6%, ischemic changes--in 29.1% rhythm disorders--in 23.7%, conduction disorders--in 10.9%. The statistical processing of the material reveals that the protraction of the electric systole of the heart, the left ventricular hypertrophy and rhythm disorders are unfavourable prognostic signs. The normal electrocardiogram present in only 9.1% of the patients, is a favourable prognostic sign. It could be one of the criteria for adequateness of hemodialysis treatment.
