Patent ID: 7970468

Claim:
A method for use with an implantable cardiac device that has discriminator parameters that the device uses to discriminate between ventricular tachycardia (VT) and supraventricular tachyarrhythmia (SVT), the method comprising: allowing a user to select a balance setting that specifies a balance between sensitivity and specificity, wherein an increase in sensitivity results in a decrease in specificity, and vice versa; and automatically adjusting a value of at least one of the discriminator parameters and/or how at least one of the discriminator parameters is used, in response to the user selecting the balance setting, wherein the at least one discriminator parameters that is automatically adjusted does not comprise the balance setting; wherein the more the balance setting favors sensitivity, then the more likely an actual VT will be characterized as VT, but the more likely an actual SVT may be characterized as VT; and wherein the more the balance setting favors specificity, then the less likely an actual SVT will characterized as VT, but the less likely an actual VT may be characterizes as VT.
