The invention relates to a wireless electrode slice. A rechargeable battery, a storage battery, a wireless transmitter and a multi-channel signal synthesizer are all mounted on a main body of the electrode slice. Due to the fact that the storage battery and the rechargeable battery are mounted on the main body of the electrode slice, electrocardiosignal acquired by an electrode tip is processed through the multi-channel signal synthesizer and then sent out through the wireless transmitter, full wireless data acquisition of the electrocardiosignal can be realized, and too much connection is avoided from affecting operation of medical workers.
