<P>PROBLEM TO BE SOLVED: To provide an improved heart monitoring system for use in EKG waveform data monitoring. <P>SOLUTION: The method and system work by first specifying a particular window of time during which the outputs of a number of different voltage threshold value detectors are to be observed (42; 16). On the basis of the observation, different detectors are specified as either active or inactive (44; 32). For those detectors specified as active, the times at which their threshold values were crossed during the specified window of time are recorded(46; 26), and on the basis of these recorded times, the temporal regularity of threshold value crossing for each detector is calculated (18; 18). The detector with both the highest regularity of occurrence and the greatest magnitude threshold value is then selected as the one likely to yield the most accurate data (58, 60; 24), unless other lower-in-magnitude detectors have the same regularity as the one with the highest magnitude (58, 80; 24). In this case, if other lower-in-magnitude detectors have time rates of occurrence two times or more the time rate of occurrence of the highest magnitude-highest temporal regularity detector, then at least one of such lower-in-magnitude detectors can be chosen as being likely to yield the most accurate data. <P>COPYRIGHT: (C)2008,JPO&INPIT |
