The invention discloses a wireless three-electrode ECG (electrocardiogram) acquisition system. A pathological data acquisition module is connected with a data processing module by a signal and is used for transmitting output data to a communication module; an MAC (Media Access Control) protocol module, a system safety and privacy protection module and a pathological data evaluation module are connected with the communication module respectively; the communication module is connected with an application module in a wireless data transmission manner; the pathological data acquisition module comprises a circuit board unit; the circuit board unit is connected with an electrode unit; and the electrode unit comprises three electrodes arranged in different positions. In the manner, the number of the electrodes is decreased, and meanwhile synthetic data are enabled to have high relevance with a 12-electrode result which is directly observed, wherein three fourths of correlation coefficients are higher than 0.75; the wireless three-electrode ECG acquisition system is simple in structure, convenient to use and easy to establish and carry; real physical conditions of patients can be reflected; and the diagnostic accuracy of the EGG acquisition system with a small number of electrodes is improved.
