Patent ID: 7381185

Claim:
A method for analyzing a physiological signal comprising the steps of: obtaining a physiological signal that comprises a set of waveforms followed by an additional waveform; wherein the set of waveforms comprises: a first waveform; a last waveform; and one or more intermediate waveforms located between the first waveform and the last waveform; obtaining a maximum slope for the first waveform, the last waveform and the one or more intermediate waveforms; obtaining a maximum slope for the additional waveform by performing the steps of: confirming the maximum slope for the additional waveform is greater than a minimum threshold; and confirming the maximum slope for the additional waveform is less than a maximum threshold; wherein the minimum threshold and the maximum threshold are derived from the maximum slopes for the first waveform, the last waveform and the one or more intermediate waveforms.
