摘要:
This invention discloses a system and a method for extracting VF signal in ECG recorded during uninterrupted CPR. The present invention provides a method for extracting a Ventricular fibrillation (VF) signal in Electrocardiography (ECG), comprising: receiving an ECG signal adding a plurality of shadowing functions to the ECG signal, to obtain a plurality of modification signals decomposing the plurality of modification signals by using an Empirical Mode Decomposition (EMD) method, to generate a plurality of Intrinsic Mode Functions (IMFs) calculating the sum of IMFs in different frequency regions based on time sequence, dividing by a number of the shadowing signal, to obtain a plurality of modification intrinsic mode functions combining the plurality of modification IMFs with the same property, to obtain a shape function modeling the shape functions to obtain a compression signal and subtracting the compression signal from the ECG signal based on time sequence, to obtain the VF signal.
