Claim Text:
1. A method performed by an implantable medical device, comprising: sensing a first cardiac signal during a known cardiac rhythm from each of a plurality of available sensing vectors, generating, for each of the plurality of available sensing vectors, a plurality of morphology templates of the first cardiac signal for each of a plurality of patient postures; sensing a second cardiac signal during an unknown cardiac rhythm using one or more of the plurality of available sensing vectors; comparing the second cardiac signal to at least a portion of the plurality of morphology templates without determining a current posture of the patient; detecting the unknown cardiac rhythm as supraventricular tachycardia in response to the second cardiac signal matching at least one of the plurality of morphology templates; detecting the unknown cardiac rhythm as ventricular tachycardia in response to the second cardiac signal not matching any of the plurality of morphology templates; and delivering a stimulation therapy in response to detecting the ventricular tachycardia.
