A real-time electrocardiosignal monitoring and processing method comprises the following steps of (1) acquiring electrocardiosignals, and filtering the electrocardiosignals; (2) calculating the real-time heart rate every second; (3) diagnosing real-time arrhythmia every second; (4) detecting heartbeat information every second, wherein the heartbeat information includes the heartbeat number, the location, the heartbeat type and the RR interval; (5) After recording, keeping statistics of the average heart rate, the highest heart rate, the lowest heart rate, the proportion of over-high heart rate, the proportion of pretty high heart rate, the proportion of normal heart rate, the proportion of pretty low heart rate, and the proportion of over-low heart rate. By the adoption of the method, signal filtration, real-time heart rate calculation, real-time arrhythmia diagnosis and the like can be conducted during electrocardiosignals acquisition, and monitoring data can be transmitted to a doctor remotely and wirelessly, so as to facilitate timely diagnosis and treatment of diseases by doctors.
