The structure is shown in fig. 1.

However, the normal electrocardiogram can only record the heart electrical activity within a certain short time, and the abnormal condition of the heart is often paroxysmal, transient or sporadic. That is, when a person's heart is abnormal, even if he goes to the hospital for examination immediately, the short static electrocardiogram of ten seconds is often unable to capture the abnormal condition, so it is necessary to monitor the heart for 24 hours or even 48 hours continuously.

Therefore, a dynamic electrocardiogram detection device has come into play, which can detect 24 or even 48 hours of electrocardiosignals.

Typical electrocardiographic devices are disclosed in the utility model patent No. CN94213324.2 entitled "standard 12-lead instantaneous electrocardiograph": the standard 12-lead instantaneous dynamic electrocardiograph consists of casing, printer on the casing, playback machine with operation keyboard, display and playback circuit, and electrocardiographic recording box with recording box circuit, and the playback machine and the recording box are connected via communication port.

The circuit structure is shown in fig. 2.

However, the dynamic electrocardiograph is large in size, and is inconvenient for a patient to carry on and completely incapable of moving or bathing. Therefore, a dynamic electrocardiograph structure with small volume and convenient carrying is needed.

Therefore, the invention also discloses a patch type dynamic electrocardiogram recorder, the structure of which is greatly reduced compared with the common electrocardiogram, and the portability of which is better. As disclosed in typical invention patents such as 201811082281.4 entitled "a patch-type dynamic electrocardiograph recorder": the utility model provides a SMD developments heart electrograph recorder, includes bottom subassembly and host computer, the bottom subassembly includes that detachable installs the bottom body on the host computer, locates the first circuit board on the bottom body, first circuit board includes first circuit board body and connects the three electrode holder on first circuit board body, and a disposable electrode piece is installed to detachable on every electrode holder.

The traditional soft and hard combination method adopts a mode that a male buckle of a button electrode and a female buckle on a host are mutually limited, so that the problem is that the operation is required to be carried out at least twice (the electrode is pasted once, and the host is installed once) before a user wears the electrode. If the wearable electrocardio equipment with more leads is adopted, the operation times of installing the electrode plates are more. Thereby greatly reducing the use experience.

In addition, since the user is not a professional doctor, when the user installs the electrode sheet, the measurement result may not be ideal due to inaccurate installation position.
