Another purpose is to provide a device including a circuit portion that does the following.

In addition, another purpose of the present invention is to collect various biological signals and accurately confirm the patient's heart disease by including various electrode arrangements or an electrode unit including two or more electrodes depending on the patient's condition.

Another object of the present invention is to provide a wearable monitoring device that can collect various biological signals from one main body by combining various types of electrode parts with one main body.

A representative configuration of the present invention to achieve the above object is as follows.
