PROBLEM TO BE SOLVED: To avoid a detection error of a peak value due to body motion, and to correctly recognize R-waves.;SOLUTION: An ECG waveform is parted at a desired time interval I0+4σ 0, a threshold value L1 is set based on the maximum value and the minimum value of the amplitude of the ECG waveform in a parted range, a local peak value larger than the threshold value L1 is detected to recognize an R-wave, a time position of this R-wave is memorized, and this is repeated in order to the last.;COPYRIGHT: (C)2001,JPO
