1. 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.
