Abstract: An evaluating method for ECG signals is provided, which comprises the steps of: a) obtaining a multichannel ECG signal of a subject over a first predetermined time period by means of a multi-lead ECG device; b) extracting a plurality of first parameters from the multichannel ECG signal; c) evaluating the quality of the multichannel ECG signal based on the plurality of first parameters; and d) presenting an indicator for indicating the quality of the ECG signal via a user interface. An ECG signal evaluating apparatus, an ECG signal acquiring apparatus, an ECG signal evaluation system and a computer program are also provided. The ECG signal evaluating method, apparatus, system and computer program of the present invention can improve the accuracy of the evaluation of the quality of the ECG signals and reduce the computational complexity of the evaluation of the quality of the ECG signals.
