When the event selection operation is performed in this way, an affirmative determination is made in step S12, and an event selection is performed in step S13, and alphanumeric information relating to the selected event is displayed on the event display unit 94 of the display unit 23. . On the event display unit 94, for example, “Vomiting around ○” and “Face color is not good” are displayed. If no event is selected, a negative determination is made in step S12, and the process in step S13 is skipped.

  In step S14, it is determined whether or not biometric information is received from the biometric sensor 6. If the biological information is received from the biological sensor 6, step S14 is affirmed and the received biological information is displayed on the biological information display unit 93 of the display unit 23 in step S15. If the biological information is not received from the biological sensor 6, a negative determination is made in step S14, and the process of step S15 is skipped.

  In this manner, the display of the event and the display of the biological information based on the character / numeric information displayed on the display unit 23 of the storage device 2 are similarly performed on the display terminal 4. Therefore, a doctor or the like who has seen the display terminal 4 can quickly and accurately grasp the action or condition of the subject or the like and biological information simultaneously with the electrocardiogram by using the character and numeral information.

  When the process of step S14 or S15 is completed, the process returns to step S1, and thereafter, the process up to step S14 or S15 is repeated. Therefore, the electrocardiogram is continuously stored and transmitted by the processing in step S1 regardless of whether or not each operation button is operated.
