摘要：
A method for assessing electrocardiogram signal quality, the method comprising: receiving heartbeat analysis data by processing electrocardiogram data acquired from an electrocardiogram monitoring device； extracting position information and width information of a QRS complex in the heartbeat analysis data； extracting an RR interval signal between two adjacent QRS complex signals； performing QRS complex signal cancellation processing on the RR interval signal to obtain an RR interval signal for which the QRS complex signal is removed； filtering the processed RR interval signal without the QRS complex signal, and performing envelope calculation on the filtered signal to obtain the average power of a noise signal of the RR interval signal for which the QRS complex signal is removed； obtaining a signal quality evaluation index according to the average power of the noise signal and the power of the QRS complex signal.
