Patent ID: 8611996

Claim:
A method of monitoring cardiac activity, the method comprising: determining, with a processor, whether a therapy module is delivering electrical stimulation to a tissue site within a patient; selecting, with the processor, a first sense mode or a second sense mode for monitoring cardiac activity of a heart of the patient based on whether the therapy module is delivering electrical stimulation to the tissue site, wherein selecting the first sense mode or the second sense mode comprises: selecting the first sense mode in response to determining the therapy module is delivering electrical stimulation to the tissue site; and selecting the second sense mode in response to determining the therapy module is not delivering electrical stimulation to the tissue site; upon selecting the first sense mode, monitoring, with the processor implementing the first sense mode, cardiac activity of the heart of the patient, wherein monitoring, with the processor implementing the first sense mode, cardiac activity of the patient comprises monitoring electrical cardiac signals of the patient and at least one non-electrophysiological parameter of the patient; and upon selecting the second sense mode, monitoring, with the processor implementing the second sense mode, cardiac activity of the heart of the patient, wherein monitoring, with the processor implementing the second sense mode, cardiac activity of the patient comprises monitoring electrical cardiac signals of the patient, and wherein the processor monitors at least one different non-electrophysiological parameter of the patient while implementing the first sense mode compared to when the processor is implementing the second sense mode.
