[PROBLEMS] To provide a blood pressure measuring device that is easy to carry, can measure blood pressure under 24-hour behavior, and enables high-quality blood pressure measurement necessary in clinical settings such as the relationship between daily recording and blood pressure. The issue is to provide. A blood pressure measurement system comprising a cuff portion that is attached to a user's wrist or upper arm and compresses a blood vessel of the wrist or upper arm, and a blood pressure measurement means that holds the cuff portion and measures a maximum blood pressure and a minimum blood pressure. A blood vessel analyzing means for analyzing a signal from the blood pressure measuring means and converting it into an arterial waveform under a 24-hour action, and a display unit for displaying information from the blood pressure analyzing means. A blood pressure measurement apparatus configured to measure blood pressure, wherein a blood pressure measurement setting unit configured to set a blood pressure measurement time under a 24-hour behavior in the blood pressure analysis unit and control the blood pressure measurement unit during the set time, and a user Agenda setting means to set daily activity contents of the patient, and the blood pressure measurement time and the daily activity contents of the user are associated with each other and the information is displayed on the display unit along with the arterial waveform. Characterized in that a agenda display means that. As a result, it is easy to carry and can easily measure blood pressure in daily life. Also, it enables high-quality blood pressure measurements necessary in clinical settings such as the relationship between daily recording and blood pressure under 24-hour behavior. Become.
