Electric shock signal detecting method and device

The invention relates to the technical field of signal detection, and provides electric shock signal detecting method and device. The electric shock signal detecting method comprises the steps of S1, acquiring an electrocardiosignal section; S3, acquiring a wave of which the absolute peak value is more than the first threshold from the electrocardiosignal, acquiring at least two waves as the selected waves, and calculating the ratio of the absolute peak values of the selected waves as the first parameters; S5, determining whether the electrocardiosignal is the electric shock signal according to the first parameters. According to the electric shock signal determining method, the ratio of the absolute peak value is used as the factor for determining the electric shock signal for the first time, so that the advantages of being accurate in determining result, small to calculate and fast to detect are realized.
