The invention discloses an electrocardiosignal artificial intelligence processing circuit based on cardiac beat differential coding, and belongs to the technical field of electrocardiosignal processing. According to the scheme, a preprocessing module is connected with a differential coding module through a cardiac beat memory, the differential coding module is sequentially connected with an activation module and a neural network classifier, and a differential network memory and a non-differential network memory are connected with the neural network classifier and are connected with a cardiac beat template memory through a template updating module; and the heart beat template memory is also connected with the differential coding module. Dynamic wakeup of the positive and abnormal cardiac beats is realized by using the waveform features of the differential cardiac beats and the adaptive threshold, so that the starting times of the artificial intelligence classifier are reduced, and the power consumption of the
