Abstract
A statistical analysis was made of long continuous records of RB intervals of the ECG of 64 patients with pyogenic surgical infections. The following indices were examined: the mean RR interval\((\overline {RR} )\), standard deviation (σ), range of variation (V), first and third correlation coefficients, excess, asymmetry,\(\overline {RR} /\sigma \) ratio, and the form of the autoregression cluster. In three groups of patients differing in the severity of their condition, the values of σ,\(\overline {RR} /\sigma \), and V were found to differ statistically significantly. These differences were clearly reflected in the size and shape of the autoregression cluster. The results suggest that the statistical chracteristics of long records of the cardiac rhythm can be used for the objective assessment of the severity of the patient's condition and the efficacy of his treatment.
