Various embodiments of a physiological waveform summarizing system of the present disclosure encompass a clinical physiological waveform (CPW) interface (20), and a physiological waveform summarizing monitor (30). In operation, the monitor (30) extracts a set of dominant physiological templates (41) from a clinical physiological waveform (CPW) communicated by the interface (20) to the monitor (30). The set of dominant physiological templates (41) represent a dominating major physiological rhythm (DMPR) of the clinical physiological waveform (CPW) temporally spanning over consecutive intervals of the clinical physiological waveform (CPW), and each dominant physiological template (41) is derived from a different interval of the consecutive intervals of the clinical physiological waveform (CPW). The monitor (30) may extract one or more secondary physiological templates (42) representative of secondary major physiological rhythm(s) (SMPR) present in the clinical physiological waveform (CPW), and provide a diagnostic major physiological rhythm log of the clinical physiological waveform (CPW) including a diagnostic plotting of the dominant physiological templates (41) and any secondary physiological template(s) (42).

Various embodiments provide systems and methods for detecting tampering with a monitoring device using biometric data.

A method for converting physiological signals includes: obtaining a first signal as a function of a time parameter, wherein the first signal represents electrocardiogram data; obtaining a second signal as a function of the time parameter, wherein the second signal represents physiological data different from the electrocardiogram data; mixing the first signal and the second signal to obtain a mixed signal; and generating a frequency spectrum pertaining to the mixed signal.
