The present invention also relates to a portable electrocardiograph with an individual calling function that has an individual calling function using a public telephone line.

(Prior technology) A portable electrocardiograph that allows patients who are at risk of a heart attack or who complain of some kind of heart abnormality to record an electrocardiogram when an abnormality occurs while living a normal life.
For example, the Holta electrocardiograph has been known for some time. By performing a Holter electrocardiogram test using this Holter electrocardiograph, abnormalities in the electrocardiogram that could not be confirmed at the time of the patient's visit to the hospital can be discovered, allowing for more accurate medical treatment.

With this Holter electrocardiograph, patients constantly wear measurement electrodes on their bodies to record electrocardiograms, and after the measurements are taken, the patients deliver the recorded data to the hospital where they visit.

In this way, the Holter electrocardiograph provides a powerful diagnostic tool for accurately grasping a patient's symptoms, but on the other hand, it is necessary to send recorded electrocardiogram data to each hospital visit, which places a burden on the patient. In addition, there is a problem in that the doctor cannot diagnose the patient's electrocardiogram until after the recorded data is delivered by the worker.

Therefore, in order to solve this problem, there is a known portable electrocardiograph that is equipped with an acoustic coupler device on the body of the electrocardiograph, and that allows the measured electrocardiogram data to be transmitted via the public line using the acoustic coupler device.

In addition, this portable electrocardiograph can transmit electrocardiogram data from an unspecified telephone, so patients can record electrocardiograms and transmit recorded data while going about their daily lives, reducing the burden on patients. is significantly reduced.

However, the fact that recorded data can be transmitted from any location means that if a major abnormality is confirmed in the patient's symptoms from the transmitted electrocardiogram diagnosis results, the doctor determines that it is necessary to visit the hospital immediately. Even in such cases, there will be an increase in the number of cases in which it becomes difficult to contact patients, and problems will arise where it will not be possible to convey requests to patients to visit the hospital.

The present invention was proposed in order to solve these problems, and provides a portable electrocardiograph with an individual call function that allows a doctor to easily call a patient who has transmitted electrocardiogram data. The purpose is to
