Patent ID: 7953476

Claim:
A system, comprising: means for storing a normal sinus rhythm output template; means for sensing cardiac signals, including tachycardia complexes; means for generating a tachycardia complex output; means for comparing the tachycardia complex output to the normal sinus rhythm output template and classifying the tachycardia complexes as either ventricular tachycardia (VT) complexes or supraventricular tachycardia (SVT) complexes based on the comparison of the tachycardia complex output to the normal sinus rhythm output template; and means for extracting tachycardia feature points from a number of the tachycardia complexes, wherein the means for generating a tachycardia complex output includes means for generating the tachycardia complex output from the normal sinus rhythm output template and the tachycardia feature points for each of the number of tachycardia complexes.
