Abstract

The reliability of telephone electrocardiogram (ECG) transmission facilities was assessed in order to carry out the computerized ECG analysis using the IBM-Bonner program. Simulated ECGs were transmitted repeatedly over telephones from an internal laboratory and from an external hospital which was 1, 000Km distant. The simulated ECG was transmitted in a highly reproducible state and with no appreciable distortion. The telephone ECG transmission facilities using the public telephone network in Japan proved to be reliable for computerized ECG analysis.
