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. | |
