<P>PROBLEM TO BE SOLVED: To provide an electrocardiographic waveform having a reduced harmonic component of a frequency spectrum by processing the electrocardiographic waveform acquired from a subject. <P>SOLUTION: This electrocardiographic waveform processor executes binarizing processing (S40) for creating binary data recording 1 at a position where R wave is present in a measured electrocardiographic waveform and 0 in other positions and further executes widening processing (S50) for expanding the width of 1 in the binary data created by the binarizing processing. The execution of a frequency analysis (S60) with respect to the widened binary data can reduce the harmonic component of the frequency spectrum. The heart rate is thus rightly measured (S70) by converting the peak frequency as the frequency analysis result into the heart rate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
