title: [Analysis of the structure of cardiac rhythm in auricular fibrillation with the aid of a specialized computer].
abstract: In 37 patients with atrial fibrillation of varying etiology the electron-computer technique was used in recording the cardiointervalogram and interval histogram and also in determining a number of indices characterizing distinctive features of the R-R intervals distribution. When analyzing the available data not was taken of a tendency towards appearance of definite types of the interval histograms, variations in the mean level of the cardiointervalogram, resembling the so-called slow waves observable in the sinus rhythm. During repeated investigations made in the same patients features of a single type in the distribution of the R-R intervals were apparent. In the course of conservative therapy of atrial fibrillation a certain stereotypy in the R-R intervals distribution was noted, it being indicative of an increased arrhythmicity in the work of the heart occurring simultaneously with the slowing down of the cardiac contractions.
