Title:
HEART RATE DETECTION METHOD AND HEART RATE DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2018175152
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect a heart rate and a time of detection of the heart rate correctly even from data of an electrocardiogram waveform having base line vibration.SOLUTION: A heart rate detection device comprises: a time difference positive/negative reverse value calculation part 3 for calculating a positive/negative reverse value of time difference of sampling data from a sampling data row of an electrocardiogram waveform; a maximum value detection part 4 for detecting a maximum value out of positive/negative reverse values in a constant time range after a sampling time of a processing object and positive/negative reverse values in a constant time range before a sampling time of the processing object; a subtraction value calculation part 5 for calculating a subtraction value obtained by subtracting the maximum value from the positive/negative reverse value of the sampling time of the processing object; an integrated value calculation part 6 for calculating a change amount of a subtraction value in a range before detection of a latest subtraction value calculated about the sampling time of the processing object by a prescribed value, and integrating a change amount; and a heart rate time determination part 7 for determining the sampling time of the processing object as the heart rate time.SELECTED DRAWING: Figure 3
