Abstract: A numeric diagnostic electrocardiometer includes an A/D converter for converting an EKG signal at each of the conventional electrodes employed in EKG analysis into numbers which are stored in an assigned memory as time and amplitude signals. The waveform is divided into time segments within which the basic waveshape is known. A programmed logic array stores abnormalities within a range for each segment of the EKG waveforms. The stored samples are read into the programmed logic array and deviation of the waveform beyond that programmed produces a numeric output. The instrument may directly translate any deviation output into a readout code referenced to a suitable manual for each combination of time and sampled data. The individually stored samples may also be read out from the memory. The instrument also includes a heart rate and heart arrythmia detection units for initial analysis of the heart.
