First Claim
Patent Images
1. 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.

22. 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.
