摘要： An object of the present invention is to provide an atrial fibrillation detection system in which: the extent of irregularity in measured pulse intervals is calculated; even in cases where an extrasystole has occurred, detection of a false positive is reduced even when the extrasystole is not excluded; and highly reliable assessment results are obtained. An atrial fibrillation detection system comprising: pulse interval measurement means 4 that measures the pulse intervals of a heart; pulse interval conversion means 8 that performs conversion, using a prescribed function; entropy computation means 9 that calculates entropy S from pulse interval images r obtained through conversion by the pulse interval conversion means 8; and comparative assessment means 10 that compares the entropy S calculated by the entropy computation means 9 and a threshold value, and that, in cases where the entropy S is greater than the threshold value, assesses that atrial fibrillation is occurring.
