US 2011/0034812 A1 · PULMONARY ARTERY PRESSURE BASED SYSTOLIC TIMING INTERVALS AS A MEASURE OF RIGHT VENTRICULAR SYSTOLIC PERFORMANCE

Abstract

Systems and methods include identifying a first portion and a second portion of a pulmonary artery pressure (PAP) signal during a cardiac cycle. A first timing interval between the first portion and the second portion is obtained and data related to the first timing interval is trended to provide a chronic physiological prognostic indicator. In an embodiment, a second timing interval is obtained from a third portion and a fourth portion of the PAP signal. Then, a function of the first and second timing intervals is trended to provide the chronic physiological prognostic indicator. In one instance, a ratio of the first interval to the second interval is calculated to provide an estimated right ventricle ejection fraction (RVEF) and the RVEF is trended.
