Abstract:
1. For use with an implantable cardiac system, a method for estimating a patient's central arterial blood pressure (CBP), the method comprising: (a) using an implanted sensor at a first site to obtain a first signal indicative of changes in arterial blood volume at the first site, the first site being along one or more peripheral arterial structures of the patient; (b) using an implanted sensor at a second site to obtain a second signal indicative of changes in arterial blood volume at the second site, the second site being a distance from the first site downstream along an arterial path of the one or more peripheral arterial structures of the patient; (c) using implanted electrodes to obtain a signal indicative of electrical activity of the patient's heart; (d) determining, using a processor, a time t (e) determining, using the processor, a time t (f) estimating, using the processor, the patient's central arterial blood pressure (CBP) based on PAT where (g) delivering at least one of heart chamber stimulation and heart shock therapy to a patient's heart, with the delivery of the at least one of heart chamber stimulation and heart shock therapy based, at least in part, upon the estimated CBP.
