ATRIAL FIBRILLATION DETECTOR, ATRIAL FIBRILLATION DETECTION METHOD, PROGRAM, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an atrial fibrillation detector, atrial fibrillation detection method, and program, capable of more accurately detecting atrial fibrillation.;SOLUTION: An atrial fibrillation detector acquires pulse wave data representing a plurality of pulse waves; on the basis of the pulse wave data, identifies a pulse rate; on the basis of the pulse wave data, calculates a peak amplitude value Ap of each of the plurality of pulse waves; on the basis of a plurality of calculated peak amplitude values Ap, calculates dispersion Da of the peak amplitude values Ap; on the basis of the pulse wave data, calculates an inter-peak time interval Tp of each of the plurality of pulse waves; on the basis of a plurality of calculated inter-peak time intervals Tp, calculates dispersion Dt of the inter-peak time intervals Tp; and on the basis of the identified pulse rate, the dispersion Da, and the dispersion Dt, determines whether the pulse wave data indicates atrial fibrillation.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
