2 results about "LA pressure" patented technology

This document describes systems and methods for cardiac monitoring and treatment using left atrial pressure. In many ways, an implantable pressure sensor in the patient's left atrium records a pressure signal. This left atrial pressure allows the calculation of the atrioventricular ratio (AVR), which is clinically relevant and can be used to guide treatment or as part of an open- or closed-loop automated treatment system.

A system and method for estimating LV filling pressure of the heart of a human patient. The system includes a data processing apparatus, an imaging system for non-invasively obtaining images of the patient's heart and for providing imaging data to the data processing apparatus, and a data input device for receiving patient specific parameters relating to BMI and systolic arterial blood pressure of the patient and for providing the patient specific parameters to the data processing apparatus. The data processing apparatus is configured to perform the method including the steps of using the imaging data and the patient specific parameters, determining an estimate of the minimum LV diastolic pressure, estimating the peak pressure drop and obtaining a maximum difference between the LA pressure and LV pressure, and calculating an estimate of the LV filling pressure.
