ABSTRACT:
Embodiments of the present invention are for use with implantable cardiac devices that have discriminator parameters that the devices use to discriminate between ventricular tachycardia (VT) and supraventricular tachyarrhythmia (SVT). A user is allowed to select a balance setting that specifies a balance between sensitivity and specificity, where an increase in sensitivity results in a decrease in specificity, and vice versa. In response to the user selecting the balance setting, a value of at least one of the discriminator parameters and/or how at least one of the discriminator parameters is used is automatically adjusted. 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. 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.
