1. A system comprising:
- a first therapy module configured to deliver electrical stimulation to a tissue site within a patient according to a set of stimulation parameter values;
a second therapy module configured to deliver at least one of a pacing, cardioversion or defibrillation therapy to a heart of the patient;
a sensing module configured to sense a cardiac signal of the heart of the patient; and
a processor configured to detect, during a time in which the first therapy module delivers electrical stimulation to the tissue site according to the set of stimulation parameter values, a potential arrhythmia of the heart based on the cardiac signal, control the first therapy module to adjust the delivery of electrical stimulation to the tissue site in response to detecting the potential arrhythmia, determine whether the potential arrhythmia is still detected after the adjustment to the delivery of electrical stimulation to the tissue site by the first therapy module, and, in response to determining the potential arrhythmia is no longer detected after the adjustment to the delivery of electrical stimulation to the tissue site by the first therapy module, initiate a modification to at least one stimulation parameter value of the set of stimulation parameter values according to which the first therapy module delivers electrical stimulation.

Abstract
Electrical crosstalk between two implantable medical devices or two different therapy modules of a common implantable medical device may be evaluated, and, in some examples, mitigated. In some examples, one of the implantable medical devices or therapy modules delivers electrical stimulation to a nonmyocardial tissue site or a nonvascular cardiac tissue site, and the other implantable medical device or therapy module delivers cardiac rhythm management therapy to a heart of the patient.
