Assessing heart failure status using morphology of a signal representative of arterial pulse pressure
First Claim
Patent Images
1. A method for assessing heart failure (HF) status of a patient, comprising the steps of:
- (a) producing a plethysmography signal that is representative of arterial pulse pressure; and
(b) assessing HF status based on the frequency characteristics of the signal.

Abstract
The heart failure (HF) status of a patient is determined based on the frequency characteristics 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.
