Patent ID: 8725238

Claim:
An electrocardiogram signal processing system comprising: a wavelet transformation unit comprising a plurality of outputs, each output being connected to one of a plurality of scales, wherein the wavelet transformation unit is adapted to transform an input electrocardiogram signal into a set of wavelets, each wavelet being output to one of the scales; a plurality of signal processing blocks, each of the signal processing blocks coupled to a respective output of the wavelet transformation unit and configured to receive and process the wavelet from the respective output, wherein the signal processing blocks provide processing functions which differ from one another; wherein the scales comprise a first scale, a second scale, a third scale, a fourth scale, a fifth scale, a sixth scale, a seventh scale, and an eighth scale; wherein each scale corresponds to a pre-determined bandwidth; wherein the signal processing blocks comprise an electrocardiogram signal reconstruction block; wherein the electrocardiogram signal reconstruction block further comprises: a first reconstruction block for the fifth to the eighth scales; a second reconstruction block for the first to the fourth scales; and a third reconstruction block for the first to the eighth scales; wherein the first reconstruction block outputs synchronized signals belonging to high-pass filtered components of the fifth to the eighth scales; the second reconstruction block outputs synchronized signals belonging to high-pass filtered components of the first to the fourth scales; and the third reconstruction block outputs signals belonging to low-pass filtered components of the first to the seventh scales.
