Abstract: Traditional methods of analyzing human peripheral brood flow (PBF) do not account for its continuous nature or small-scale variation. Sequel transformation is presented as a new methodology for measuring these variations. This analysis generates a richer record of aspects of activation of the autonomous nervous system than traditional interbeat-interval (IBI) measurement. Presumably, in addition to heartbeat (i.e., IBI), other information can be extracted that is consistent with the influence of several physiological and psychological factors. This kind of variation is reflected in the PBF signal. After determining and extracting relevant events from vascular volume data generated by sequel transformation, we demonstrate the use of template analysis to analyze patterns of events as time courses of activation. All procedures are included in the computer program VASC Analyzer.
