First Claim
Patent Images
1. An implantable cardioverter defibrillator (ICD) system, comprising:
- a sensing circuit configured to receive a cardiac electrical signal via a sensing electrode vector and sense cardiac events from the cardiac electrical signal;
a therapy delivery circuit configured to deliver electrical pacing pulses to a heart of a patient via a pacing electrode vector; and
a control circuit coupled to the sensing circuit and the therapy delivery circuit and configured to automatically switch between a sensing without pacing mode and a temporary pacing mode, and further configured to;
detect asystole based on the cardiac electrical signal while operating in the sensing without pacing mode,in response to detecting the asystole, determine if asystole backup pacing is enabled, andautomatically switch to the temporary pacing mode in response to the asystole backup pacing being enabled.

Abstract
An implantable cardioverter defibrillator (ICD) receives a cardiac electrical signal by a sensing circuit while operating in a sensing without pacing mode and detects asystole based on the cardiac electrical signal. The ICD determines, in response to detecting the asystole, if asystole backup pacing is enabled, and automatically switches to a temporary pacing mode in response to the asystole backup pacing being enabled. Other examples of detecting asystole and providing a response to detecting asystole by the ICD are described herein.

43. A non-transitory, computer-readable storage medium comprising a set of instructions which, when executed by a control circuit of an implantable cardioverter defibrillator (ICD) system, cause the system to:
-
receive a cardiac electrical signal by a sensing circuit of an ICD; while operating in a sensing without pacing mode, detect asystole based on the cardiac electrical signal; in response to detecting the asystole, determine if asystole backup pacing is enabled, and automatically switch to a temporary pacing mode in response to the asystole backup pacing being enabled.
