Abstract
A method of enhancing the signal-to-noise ratio (SNR) of measured electrocardiogram (ECG) signals is provided. The method includes the steps of providing at least three cardiac input signals derived from the measured ECG signals Sand forming a first estimate USfrom each of at least three pairs of input signals. Moreover, the method includes the steps of forming a second estimate USfrom each of at least three input signals; comparing Sthe polarity and the amplitude of a first and second estimate U, Uto at least one threshold T; generating Sa composite signal X, wherein the polarity and the amplitude of the composite signal X depend on the result of the comparison; and using Sthe generated composite signal X to produce an output signal with enhanced signal-to-noise ratio (SNR). Furthermore, a corresponding cardiac device is also provided.
