Automatic Measurement of the Electrocardiogram by Digital Computer

An on-line system for the automatc measurement or diagnosis of ECG was devised, whereby operation for data acquisition and processing of ECG was made in a simpler and more effective way. Twenty-five patients' ECG could be automatically recorded and processed by the system a day. Pattern recognition and measurement of ECG was successfully performed by a parameter of radial velocity of the spatial vectorcardiogram. The beginning and end of ECG waves were accurately estimated in ninety-seven per cent of one hundred subjects with various ECG findings. Consideration on several methods to improve the system was made on hard ware as well as on soft ware.
