The present invention relates to a medical-related technology, and in particular to an electrocardiogram signal detection device and system.

FIG. 4 is a block diagram of an ECG signal detection system according to some exemplary embodiments of the present invention. Referring to FIG. 4, the ECG signal detection system 400 may include an ECG signal detection device 100 and a server 200. The ECG signal detection device 100 has a similar structure and operation to the ECG signal detection device of FIG. 1, so it is not described in detail here. The ECG signal detection device 100 may be coupled to the server 200. The server 200 may generate a twelve-lead ECG signal based on the three differential signals generated by the ECG signal detection device 100 to monitor the twelve-lead ECG signal.

In this way, the server 200 can perform machine learning-related operations on the three differential signals to generate a 12-lead ECG signal. In other words, the server 200 only needs three differential signals generated by the V1, V2, V3, V4, V5 and V6 lead signals to generate the user's 12-lead ECG signal.

Furthermore, the server 200 can store all the twelve-lead ECG signals generated by the ECG signal detection device 100 in the past (for example, stored in a database (not shown) in the server 200 or an external database (not shown)). The terminal device 410 or any of the monitoring devices 420(1)-410(N) can request the server 200 for the twelve-lead ECG signals detected at any time to monitor the user's twelve-lead ECG signals in real time or to track the history. In this way, the user can immediately notice the abnormality of his or her heart rhythm through the display of the terminal device 410. Medical personnel can also immediately notice abnormal heart rhythm of the user through one or more of the monitoring devices 420 ( 1 ) to 410 (N).

With the above structure, the ECG signal detection system 400 of the present invention can detect the lead signals of the chest leads of the user at any time, and generate three differential signals according to the lead signals to monitor the twelve-lead ECG signals generated by the three differential signals. In this way, the user or the medical staff treating the user can monitor the user's heart rhythm at any time.

In summary, the ECG signal detection device of the embodiment of the present invention is easy to attach to the user and uses fewer electrodes to generate a twelve-lead ECG signal corresponding to the user's heart rhythm in real time. Furthermore, the electrodes are attached to six chest lead electrodes among the ten electrodes that generally detect twelve-lead ECG signals. In this way, medical personnel only need to attach these electrodes to the positions corresponding to the general chest lead electrodes, and do not need to attach these electrodes to other specific positions. In addition, the ECG signal detection system of the embodiment of the present invention can facilitate users or medical personnel to monitor the twelve-lead ECG signal corresponding to the user's heart rhythm in real time for a long time.
