Abstract: A biological information processing system includes a processor including hardware. The processor performs: acquisition processing in which pulse wave information is acquired; processing in which analysis processing on the pulse wave information is performed to generate analysis result information; and output processing in which the analysis result information that is generated is outputted. The processor generates the analysis result information for identifiably displaying a pulse wave abnormality period detected on the basis of the analysis processing and for displaying at least one of action information, psychological state information, external environment information and location information of a user.

Abstract: A biological information detection device which detects an arrhythmia on the basis of pulse wave information, performs control on measurement of an electrocardiogram on the basis of the detection result, and thereby restrains failure to record the electrocardiogram at the time of occurrence of an arrhythmia, or the like. The device includes a pulse wave information measuring unit which measures pulse wave information, an electrocardiogram measuring unit which measures an electrocardiogram, and a control unit which performs at least one of power supply control on the electrocardiogram measuring unit, storage control for electrocardiogram measurement result information measured by the electrocardiogram measuring unit, and notification control to output notification information about the measurement of the electrocardiogram using the electrocardiogram measuring unit, to a user, if it is determined that an arrhythmia is detected on the basis of detection result information obtained by analysis processing based on the pulse wave information.
