Clinical observation shows that arrhythmia is usually sporadic, the occurrence time and frequency are not fixed, and data with great significance can be obtained generally by long-term monitoring. In order to meet the requirement of continuous electrocardiographic monitoring, a dynamic electrocardiographic technology is developed, such as a typical Holter electrocardiograph, but the further development of the dynamic electrocardiographic technology is limited by a plurality of factors, such as large and heavy host, wired transmission, insufficient remote management and the like.

With the rapid development of microelectronic communication technology, wireless dynamic electrocardiographic monitoring technology starts to enter the field of vision of people, such as an electrocardiographic patch body. The electrocardio paster body is generally small and exquisite and portable, and can be used for carrying out electrocardio monitoring for a certain time. When the electrocardio patch body is used, the electrocardio patch body is usually attached to the surface of a human body through a specific adhesive tape, and the electrocardio signal is acquired and analyzed through the contact of a wet electrode or a dry electrode with the skin. At present, an electrode on an electrocardio patch body is arranged on the bottom surface of the patch body close to the skin; when the electrocardiosignals are statically detected, a glue paste is added between the electrocardio patch body and the skin; when the electrocardiosignal is detected in the motion state, a larger dressing is needed to be added to cover the electrocardio patch body, so that the electrocardio patch body is more firmly fixed on the surface of the skin to reduce the motion interference.
