    摘要: 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.

    摘要: A system comprising an implantable medical device (IMD) includes an implantable heart sound sensor to produce an electrical signal representative of at least one heart sound. The heart sound is associated with mechanical activity of a patient's heart. Additionally, the IMD includes a heart sound sensor interface circuit coupled to the heart sound sensor to produce a heart sound signal, and a signal analyzer circuit coupled to the heart sound sensor interface circuit. The signal analyzer circuit measures a baseline heart sound signal, and deems that an ischemic event has occurred using, among other things, a measured subsequent change in the heart sound signal from the established baseline heart sound signal.
