1. A method comprising:
- determining a first characteristic of a first electrical cardiac signal of a patient sensed by a first implantable medical device (IMD);
determining a second characteristic of a second electrical cardiac signal of the patient sensed by the first IMD while a second IMD delivers electrical stimulation to a tissue site within the patient, wherein the first and second IMDs are implanted within the patient;
determining an electrical noise status based on the first and second characteristics; and
generating a notification based the electrical noise status.

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.

16. A system comprising:
-
a first implantable medical device (IMD) that senses first and second electrical cardiac signals of a heart of a patient; a second IMD that delivers a second electrical signal to a patient, wherein the first IMD senses the second electrical cardiac signal while the second IMD delivers electrical stimulation to a tissue site within patient; and a processor that determines a first characteristic of the first electrical signal and a second characteristic of a second electrical cardiac signal, determines an electrical noise status based on the first and second characteristics, and generates a notification based the electrical noise status. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
