Anti-tachyarrhythmia system with selectively activated detection enhancements
First Claim
1. An external system for communicating with an implantable cardioverter defibrillator (ICD), the ICD having a plurality of detection enhancement modules configured to perform detection enhancements being algorithms for detecting and analyzing indications of type of tachyarrhythmia, the external system comprising:
- a user interface configured to present a plurality of available classification modes and receive a user selection of a classification mode from the plurality of available classification modes, the available classification modes each specifying whether each detection enhancement module of the plurality of detection enhancement modules, including a morphology analyzer configured to analyze a correlation between a tachyarrhythmic waveform of a cardiac signal sensed during a detected tachyarrhythmia episode and a template waveform, is to be activated or deactivated according to a pre-selected set of none, one, or more of the detection enhancements.

Abstract
A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD detects a tachyarrhythmia episode and classifies the detected tachyarrhythmia episode using none, one, or more of detection enhancements selected according to a selection command including a classification mode. The detection enhancements are each an algorithm for detecting and analyzing one or more indications of a type of the detected tachyarrhythmia episode. The external system allows a user to select the classification mode from a plurality of available classification modes each using none, one, or more of the detection enhancements.
