Abstract:
1. A system for estimating cardiac pressure within a patient using an implantable medical device for implant within a patient, the system comprising: an immittance detection system operative to detect a value representative of electrical immittance within the heart of the patient; an immittance-based electrical conduction delay estimation unit operative to estimate an electrical conduction delay in the heart of the patient from the value representative of immittance; and a conduction delay-based cardiac pressure estimation unit operative to estimate cardiac pressure within the patient from the estimated electrical conduction delay; a controller configured to at least one of, based at least in part on the estimated cardiac pressure: generate instructions for therapy to at least one end user, automatically deliver medication using a drug pump, or automatically adjust pacing parameters of the implantable medical device.
