Appraisal of the Sicard (Siemens) system for the automated evaluation of ECG's is reported. 528 ECG's were simultaneously recorded on paper and magnetic tape and examined by a group of specialists and the 404/3 computer forming part of the system, followed by a check on an IBM computer. A very high percentage of fits was noted and a favourable judgment is passed on the system.
An assessment was made of the accuracy and practicability of the Sicard system (Siemens). This employs the Minnesota and USPHS codes. A series of 64 ECG's was examined. Results obtained automatically were compared with those given by a cardiologist and a second processing on the computer. The only differences of importance consisted of classification discrepancies, particularly in the case of arrhythmia and atypical pictures during the ventilogram recovery stage. While further improvement of the system is to be hoped for, it nevertheless makes valuable work of long-term significance possible.
This study highlights the various parameters considered for experimenting automatic equipment correctly. By applying such parameters to experiments with the "Sicard" system (Siemens) for automatic ECG reading, the usefulness of the system for its declared purpose, i.e. mass screening and epidemiological research, has been demonstrated.
