A QRS Detection Algorithm Based on the Empirical Mode Decomposition

The possibility and efficiency of a way by the Empirical Mode Decomposition (EMD), a recently popular signal analysis method, to check the position of QRS in an ECG is discussed in this paper. The result displays that the high frequency parts of Intrinsic Mode Functions (IMF) in the ECG are effective to separate the feature point of QRS from the ECG. That is verified by standard signals and the accurate rate is relatively high.
