Abstract
A method and apparatus for monitoring and measuring the hemodynamic status of a patient's pulmonary pressure and right atrial pressure. The aforementioned is achieved by using an implanted absolute pressure sensor located in the right ventricle, coupled to an implantable monitoring device, which records pressure values in response to a combination of sensed electrical depolarizations of the atrium and ventricle and occurrence of first and second derivatives of the pressure signal having values less than zero.
