Abstract
An implantable medical device comprises a sensing module configured to obtain electrical signals from one or more electrodes and a control module configured to process the electrical signals from the sensing module in accordance with a tachyarrhythmia detection algorithm to monitor for a tachyarrhythmia. The control module detects initiation of a pacing train delivered by a second implantable medical device, determines a type of the detected pacing train, and modifies the tachyarrhythmia detection algorithm based on the type of the detected pacing train.
Claims16
A device comprising:
- a therapy module configured to deliver electrical stimulation therapy to a patient;
- a sensing module configured to sense a cardiac electrical signal of the patient;
- and
- a control module configured to:
- process the cardiac electrical signal in accordance with a tachyarrhythmia detection algorithm to monitor for a tachyarrhythmia;
- detect initiation of a pacing train delivered by a second device;
- determine, based on a cycle length of the detected pacing train, that the detected pacing train is an anti-bradycardia pacing train;
- modify the tachyarrhythmia detection algorithm based on determining that the detected pacing train is an anti-bradycardia pacing train;
- determine, based on the modified tachyarrhythmia detection algorithm, whether the cardiac electrical signal indicates an arrhythmia;
- and
- control, based on determining that the cardiac electrical signal indicates the arrhythmia, the therapy module to deliver the electrical stimulation therapy to the patient.
