Abstract
A computerized apparatus for processing a multi-lead ECG beat signal to generate a residual signal has an averager unit for providing a template ventricular beat signal, and a subtraction unit for subtracting the template beat signal from the multi-lead ECG beat signal to generate the residual signal. An alignment stage is disposed before the subtraction unit and compares the template beat signal with an intermediate beat signal in the alignment parameter generator. A further subtraction unit may be provided to receive the multi-lead ECG beat signal and to subtract a signal representative of an estimated atrial signal therefrom to generate the intermediate beat signal. The alignment stage also modifies the template beat to increase the relative alignment of the two signals, with respect to at least spatial, characteristics, and emits the modified signal as an output for use by the subtraction unit as the template beat signal.
