Abstract
Methods, systems, and apparatus for detecting and/or validating a detection of a state change by matching the shape of one or more of an cardiac data series, a heart rate variability data series, or at least a portion of a heart beat complex, derived from cardiac data, to an appropriate template.
Claims22
A computer readable program storage unit encoded with instructions that, when executed by a computer, perform a method for indicating an occurrence of a state change, comprising:
- obtaining data relating to at least a portion of a heart beat complex from a patient;
- comparing said at least said portion of said heart beat complex with a corresponding portion of a first reference heart beat complex template of said patient;
- and,
- indicating an occurrence of a state change based upon a determination that said heart beat complex fails to match said first reference heart beat complex template.
A computer readable program storage unit encoded with instructions that, when executed by a computer, perform a method for indicating an occurrence of a state change, comprising:
- obtaining data relating to at least a portion of a heart beat complex from a patient;
- comparing said at least said portion of said heart beat complex with a corresponding portion of a first reference heart beat complex template of said patient, wherein said first reference heart beat complex template comprises at least a first matched filter;
- generating a time series of outputs of said first matched filter;
- building a second matched filter from said time series of outputs of said first matched filter;
- and,
- indicating an occurrence of a state change based upon a determination that said output of said second matched filter matches a matched filter output template.
