Title: METHOD FOR DENOISING ELECTROCARDIO SIGNAL AND DEVICE
Abstract:
A method for denoising an electrocardio signal and a device, the method comprising: performing initialization processing on a first filter according to a preset parameters value (S101); acquiring an electrocardio signal (S102); constructing a mirror extension signal of the electrocardio signal (S103); executing double bilateral filtering after the mirror extension signal is inputted to the first filter so as to obtain a first filter signal which does not contain power frequency noise (S104). The first filter need only be initialized and the mirror extension signal of the electrocardio signal inputted to the first filter so as to perform a double bilateral filtering processing, and the power frequency noise in the electrocardio signal may thus be removed, achieving denoising of the electrocardio signal. The steps of said method are simple, and thus the amount of calculation is small and requirements for system performance are low. Compared with an original electrocardio signal, the quality of the electrocardio signal is improved to a certain extent, and a better electrocardiogram imaging effect is obtained.
