[Reliability of the ECG analyzer EAK-2 in screening tests].

In the last years the number of derivated electrocardiograms with several approaches to the problem has permanently increased. Therefore, the computer analysis seems to be obvious. The reliability of the analogo-digital-computer Express Analyzer Cardiograph EAC-2, Medexport Moscow, was for the employment for occupational medical examinations investigated on 252 experimental persons and compared with the independent manual analysis, which was carried out by two physicians. 80 per cent of the available ECGs were automatically correctly arranged into groups and all the inconspicuous electrocardiograms were sorted out, since it occurs on no account that an electrocardiogram which was recognized as pathological by means of manual analyses, was analysed as falsely normal by the computer EAC-2. Consequently, EAC-2 at low technical interference susceptibility may be very useful for the ECG-diagnosis by means of the computer during the screening investigations.
