Patent ID: 8271080

Claim:
A system for assessing decongestive therapy delivered to a heart failure patient, comprising: an implantable sensor configured to sense a physiologic parameter indicative of the patient's diuresis status responsive to delivery of a decongestive therapy; and a processor coupled to the implantable sensor, the processor configured to determine if the patient is being subject to over-therapeuting when a target level of patient diuresis has been achieved based on a relationship between the sensed physiologic parameter and a threshold developed for the patient, produce a first output in response to determining that the target level of patient diuresis has been achieved, and produce a second output in response to determining that the patient is being subject to over-therapeuting, wherein the second output comprises an alert indicating detection of over-diuresis of the patient, wherein the relationship is based on a rate of change of the sensed physiologic parameter relative to the threshold.
