title: [Possibilities of the automatic data processing in differential diagnosis of arteriosclerotic cardiosclerosis and rheumatic heart disease complicated by auricular fibrillation].
abstract: The possibility of applying some mathematical methods for automating the process of differential diagnosis between atherosclerotic cardiosclerosis and rheumatic heart diseases complicated by auricular fibrillation, based on employing computing technique in processing the cardiointervalographic findings, is discussed. The processing of cardiointervalograms taken in 2 groups of patients with diseases in question (totaling 49 persons) aged over 45 evidenced that in the differential diagnosis mathematical expectation and dispersion of the R-R intervals duration are most informative signs. It is shown that for the purpose of automatic diagnosis of atherosclerotic cardiosclerosis and rheumatic heart diseases complicated by auricular fibrillation with the method under discussion the sufficient length of cardiointervalograms equals 130--150 R--R-intervals.
