Abstract
An implantable medical device comprising a signal generator configured to generate and deliver anti-tachyarrhythmia pacing (ATP) to a heart of a patient and processing circuitry. The processing circuitry is configured to detect an enable event, responsive to detecting the enable event, enable the delivery of ATP by the signal generator, detect a disable event indicating that another implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock, and responsive to detecting the disable event, disable delivery of ATP.
Claims11
A method comprising:
- detecting, by an implantable medical device configured to deliver anti-tachyarrhythmia pacing (ATP) to a heart of a patient, an enable event;
- responsive to detecting the enable event, enabling, by the implantable medical device, the delivery of ATP;
- responsive to detecting the enable event, starting, by the implantable medical device, a timer;
- detecting, by the implantable medical device, a disable event indicating that another implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock, wherein detecting the disable event comprises detecting that the timer has reached a time limit without requiring communication between the implantable medical device and the other implantable medical device;
- and
- responsive to detecting the disable event, disabling, by the implantable medical device, delivery of ATP.
A method comprising:
- detecting, by an implantable medical device configured to deliver anti-tachyarrhythmia pacing (ATP) to a heart of a patient, an enable event;
- responsive to detecting the enable event, enabling, by the implantable medical device, the delivery of ATP;
- responsive to detecting the enable event, starting, by the implantable medical device, a timer;
- detecting, by the implantable medical device, a disable event indicating that another implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock, wherein detecting the disable event comprises detecting that the timer has reached a time limit;
- responsive to detecting the disable event, disabling, by the implantable medical device, delivery of ATP;
- detecting, by the implantable medical device via a plurality of electrodes, cardiac therapy activity;
- and
- modifying, by the implantable medical device, the timer based on detection of the cardiac therapy activity.
A method comprising:
- detecting, by an implantable medical device configured to deliver anti-tachyarrhythmia pacing (ATP) to a heart of a patient, an enable event;
- responsive to detecting the enable event, enabling, by the implantable medical device, the delivery of ATP;
- detecting, by the implantable medical device, a disable event indicating that another implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock, wherein detecting the disable event comprises detecting delivery of a threshold number of anti-tachyarrhythmia shocks, thereby suggesting that the other implantable medical device cannot be relied upon to deliver an anti-tachyarrhythmia shock;
- and
- responsive to detecting the disable event, disabling, by the implantable medical device, delivery of ATP.
