An on-line system to analyze cardiac arrhythmias was developed by the use of a small scale digital computer. In this system, the electrocardiographic signals were fed into the computer, being adjusted within the input range by a buffer amplifier. The analog signals of each electrocardiogram were converted to the digital form at the rate of 1, 000 per second for 20 seconds by the analog-to-digital converter insatlled in the computer. Thus, the digitized electrocardiogram was processed by the diagnostic program. The computation time for the parameter measurements and the interpretation of an electrocardiogram by this system was about 15 seconds. The automated systems of this type would serve as a diagnostic aid for physicians in the routine electrocardiographic interpretation and the mass screening of heart diseases.
