DEVICE FOR MONITORING ACUTE DECOMPENSATED HEART FAILURE

摘要

An implantable medical device (100) comprises an impedance determiner (120) for determining a cardiogenic impedance signal (20, 30) based on electric signals sensed by connected electrodes. A parameter calculator (130) processes the impedance signal (20, 30) to calculate an impedance parameter representative of the cardiogenic impedance in connection with the diastolic phase of a heart cycle. This parameter is then employed by the device (100) for monitoring acute decompensated heart failure status of a subject (1).
