1. A method comprising:
- determining whether a therapy module is delivering electrical stimulation to a tissue site within a patient;
sensing electrical cardiac signals according to a first sense mode when the therapy module is delivering electrical stimulation to the tissue site; and
sensing electrical cardiac signals according to a second sense mode when the therapy module is not delivering electrical stimulation to the tissue site, wherein the first and second sense modes define different sense vectors for sensing the electrical cardiac signals.

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.
