<P>PROBLEM TO BE SOLVED: To provide an electrocardiogram (ECG) analytic apparatus in which an accurate ST potential can be obtained by extracting the ST potential at a position stable for a QRS group, and an ECG analytic method using this ECG analytic apparatus. <P>SOLUTION: This apparatus is provided with an ECG signal generating means 11 for generating an ECG signal from electric signals appearing in a plurality of ECG electrodes 10, a generation time phase detecting means 12 for performing mutual correlative processing between the ECG signal generated by the ECG signal generating means 11 and a template waveform set corresponding to the waveform of the QRS group contained in that ECG signal and detecting the location of the template waveform on a time base when the correlative value of that mutual correlative processing is to become maximal as a generation time phase of the QRS group and at ST potential extracting means 17 for extracting the voltage value of the ECG signal after setting time from the generation time phase of the QRS group detected by the generation time phase detecting means 12 as the ST potential. <P>COPYRIGHT: (C)2003,JPO |
