[Ways to increase the information content in the automatic processing of instrumental data in cardiology]

New algorithms for the analysis of sinus rhythm and doppler-cardiogram of the posterior wall of the left ventricle are suggested. Clinically invormative signs have been revealed: number of classes of R--R intervals, distance between the centers of the classes, regular distribution of R--R intervals according to classes, and the value of the doppler-cardiogram spectrum harmonics I/II ratio. The possibility of using these signs in the systems of automatic analysis of data in examination of patients with ischemic heart disease is shown.
