Abstract:
1. An electrocardiograph system comprising: means for sensing a plurality of electrocardiograph signals, the signals comprising cardiac data and a succession of waves; means for independently identifying the QRS complex in each wave; means for signal-averaging the QRS complex in each wave; means for band-pass filtering the signal-averaged QRS complex in a high frequency range thereby deriving high frequency components of the QRS complex, wherein the means for band-pass filtering passes frequencies from 150 Hz to 250 Hz; means for detecting a reduced amplitude zone within the high frequency components of the QRS complex in each wave relating to cardiac function, the reduced amplitude zone within the high frequency components of the QRS complex comprising RAZ data; means for relating at least three of the detected reduced amplitude zones in accordance with predetermined criteria to develop cardiac diagnoses; and means for displaying the cardiac and RAZ data in real time on a monitor.
