1. A method of patient signal analysis, comprising: receiving patient signal data; identifying at least one region of interest within a cycle of a waveform of the patient signal data; segmenting the identified region of interest into portions using amplitude percentage categories; generating a sequential morphological data series by compiling time intervals of the segmented portions; calculating one or more sequential signal parameters based on the sequential morphological data series; and generating a report based at least in part on the one or more sequential signal parameters.
