Background

Wearable electronic devices including smartwatches and bracelets are capable of providing users with various functions as smart terminals, monitoring the motion characteristics and even biological characteristics of the users through specific sensors, and providing various information of the users including from time tracking to health-related information. The mechanism of generation of the electrocardiosignals is that a series of electrophysiological changes are generated in the beating process of the heart, and the electrophysiological changes are transmitted to the body surface. These electrical signals can be picked up by electrodes, spread out on the time axis as cardiac waves, called body surface ECG. The heart is a subject, and thus its electrophysiological changes are transmitted to different locations on the body surface. In order to reflect the change of the electrocardio more comprehensively, electrodes can be arranged at different positions of the body surface to collect signals. At present, a lot of intelligent wearable electronic devices capable of detecting electrocardiosignals exist, and the basic detection principle is to acquire the electrocardiosignals of two upper limbs of a human body to acquire an ECG based on two electrodes.
