Title:
INSTANTANEOUS HEARTBEAT RELIABILITY EVALUATION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/225662
Kind Code:
A1
Abstract:
The instantaneous heartbeat reliability evaluation device according to an embodiment of the present invention is provided with an extraction means for extracting waveforms having a maximum value corresponding to the depolarization of the heart from a biological signal of a subject; a first calculation means for calculating an interval between two extracted waveforms adjacent to each other in time series; a division means for dividing a signal outputted from a measuring means into signals in respective preset time periods; a second calculation means for calculating a feature amount of the potential of each of the divided signals; a first evaluation means for assessing whether a measured state of each of the divided signals is normal or abnormal on the basis of the feature amount; and a second evaluation means for evaluating the measured state of each of two adjacent extracted waveforms, on the basis of the result of evaluation by the first evaluation means, and evaluating the reliability of a measured state of the waveform interval calculated by the first calculation means, according to the type of the evaluated measured state of the waveforms.
