1. A cardiac rhythm management (CRM) system, comprising:
- an implantable cardioverter defibrillator (ICD) including;
a cardiac sensing circuit configured to sense one or more cardiac signals including an atrial electrogram;
a rate detector configured to detect an atrial rate from the atrial electrogram;
a plurality of functional modules each configured to be activated and deactivated in response to a selection command, the functional modules each performing a tachyarrhythmia classification or therapy control function using the atrial rate and an atrial tachyarrhythmia rate threshold; and
a threshold circuit configured to receive a unified threshold value and set the atrial tachyarrhythmia rate threshold for each activated functional module of the plurality of functional modules to the unified threshold value.

Abstract
A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD includes a plurality of functional modules performing tachyarrhythmia classification and therapy control functions using atrial tachyarrhythmia rate thresholds that are set to a unified value. In one embodiment, the CRM system allows a user to activate and deactivate each of the functional modules and program the unified value using the external system.

11. A method for operating a cardiac rhythm management (CRM) system, the method comprising:
-
sensing one or more cardiac signals including an atrial electrogram; detecting an atrial rate from the atrial electrogram; activating one or more features of a plurality of functional features in response to a selection command, the functional features each associated with a tachyarrhythmia classification or therapy control function of an implantable cardioverter defibrillator (ICD) performed using the atrial rate and an atrial tachyarrhythmia rate threshold; receive a unified threshold value; and setting the atrial tachyarrhythmia rate threshold for each of the activated one or more features to the unified threshold value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
