Abstract: An electrocardiographic transmitter executes statistical processes for an electrocardiographic signal to calculate an average value HRav of a heart rate HR in a predetermined period of time. In a case where the average value HRav of the heart rate HR is abnormal, the electrocardiographic transmitter continuously transmits electrocardiogram data based on the electrocardiographic signal to a terminal. The terminal receives and transfers the electrocardiogram data as it is to a host device. The host device stores therein and supplies the transferred electrocardiogram data for a diagnosis by a medical worker. Thus, the state of a subject's heart can be monitored over the long term.
