Implantable medical device

摘要

Implantable medical device comprising pressure sensing means (4) to measure right ventricular pressure of a heart including a pressure sensor (6) adapted to be positioned in the right ventricle of the heart, to measure said pressure and to generate a pressure signal (8) in response of said measured pressure, the pressure sensing means comprises a pressure signal processing means (12) and a timing means (14). The processing means is arranged to determine from said pressure signal, using diastolic timing signals from the timing means (14) based on said pressure signal (8) identifying the diastolic phase, a diastolic pressure signal (20) representing the ventricular pressure only during the diastolic phase of the heart cycle.
