摘要
The heart failure (HF) status of a patient is determined based on the morphology of a signal representative of arterial pulse pressure. The signal can be a plethysmography signal that is produced by a implantable sensor or a non-implanted sensor. The signal can be produced by a chronically implantable sensor. In one embodiment, a time derivative signal is produced based on a signal representative of arterial pulse pressure. The time derivation signal can be used to determine maximum and minium peaks of,the signal representative of arterial pulse pressure. Alternatively, HF status can be assessed directly from the time derivative signal.
