[Computer calculation of echocardiographic indices].
The objective of the study was to determine the degree of discrepancy in the data from echocardiographic indices, determined by the original Bulgarian apparatus "Echocomputer" (engineer Daskalov) and by two independently working researchers as well as the accuracy of repetition by one researcher. M-echocardiographic records were used for that purpose of 22 patients with various cardiopathies, the indices determined by the computer were compared with the data of the same indices but obtained by calculations according to the well known classical formulae. Two statistical methods were used--variation and correlation analysis. No statistically significant difference was established between the compared values of Echocomputer and considerable correlation dependence in the comparison of the data from two different ways of calculation of EchoCG-indices.
