A biosignal measuring device has a first information acquisition module, a second information acquisition module, a first calculation module, a second calculation module, a third calculation module, a heartbeat interval estimation module, a determination module, and an output module. The first information acquisition module acquires the pulse wave signal. The second information acquisition module acquires an electrocardiogram signal. The first calculation module calculates a pulse wave velocity based. The second calculation module determines a heartbeat interval. The third calculation module calculates a relationship between pulse wave velocity and the heartbeat interval. The heartbeat interval estimation module estimates an estimated heartbeat interval based on pulse wave velocity and calculated relationship. The determination module determines whether the position of the first and second information acquisition modules has changed based on the heartbeat interval and the estimated heartbeat interval. The output module outputs information. |
