ISCHEMIA DETECTION USING PRESSURE SENSOR
First Claim
1. A system comprising:
- an implantable chronic pulmonary artery (“
PA”
) pressure sensor, configured to chronically sense a pulmonary artery pressure (“
PAP”
) signal of a PA; and
an implantable or external processor, communicatively coupled to the PA pressure sensor to receive PAP information, wherein the processor is configured to use the PAP information to compute an indication of a reduction of blood supply to at least a portion of a heart.

Abstract
This document discusses, among other things, a system and method for sensing a pulmonary artery pressure (“PAP”) signal of a pulmonary artery (“PA”) and computing an indication of a reduction of blood supply to at least a portion of a heart using information from the PAP signal. The reduction of blood supply to at least a portion of the heart can be detected using a PAP signal characteristic or measurement, using a change in the PAP, using an interval between multiple PAP signal features, using a mitral valve performance, or using information from the PAP and information from a different physiological signal, including a cardiac signal, a heart sound signal, right ventricular pressure signal, a left ventricular pressure signal, a blood pressure signal, and an oxygen saturation signal.
