  "textContent": "The occurrence of a sudden change in physical condition is detected. In a physical condition determination device a heart rate-relate index calculation unit specifies an appearance time of a sign of a sudden change in heart rate, from a time-series waveform of an index corresponding to a variation in the heart rate (heart rate-related index) and a blood pressure-related index calculation unit specifies an appearance time of a sign of a sudden change in blood pressure, from a time-series waveform of an index corresponding to a variation in the blood pressure (blood pressure-related index). A physical condition sudden change determination unit determines that a sudden change in physical condition (physical condition sudden change) has occurred in a case where these appearance times are both within a predetermined time. This enables the determination in which the sudden change in the heart rate and the sudden change in the blood pressure are taken into consideration, to enable the detection of the physical condition sudden change.",
