[Changes in the end part of the ECG ventricular complex under the effect of digitalis preparations and their combination with metabolic preparations].

Analysis of the dynamics of changes in the end part of the ECG ventricular complex in 311 patients with rheumatic heart disease and stages IIA, IIB, and III circulatory insufficiency after treatment with preparations of digitalis and their combination with biologically active substances (orotic acid, vitamin B12, calcium pantothenate, ATP, methionine, inosi-F) is presented. When digitalis glycosides are used with preparations that have an effect on the nucleic acid synthesis and energy production, the "digitalis--induced" changes in the end part of the ECG ventricular complex are less marked while the clinical effect of treatment is more appreciable
