Patent ID: 8888698

Claim:
A system for determining a stressor-based reference baseline for use in heart failure assessment, comprising: a programmer to receive monitoring of a patient that was performed during an observation time period while the patient performed prescribed physical stressors and while pacing stimulus stressors were applied to a medical device of the patient; and a server, comprising, a storage module to store physiological measures from the observation period into a patient care record comprising at least one of direct measures regularly recorded on a continuous basis by the medical device and measures derived therefrom; a reference baseline module to identify those of the physiological measures that originate from the observation time period as a reference baseline for the patient; and an evaluation module to evaluate the reference baseline and those physiological measures originating subsequent to the observation period, comprising: an analyzer module to compare the direct measures and derived measures to the physiological measures from the observation period to detect a patient status comprising one of a status quo and a change in cardiac performance of the patient; and a comparison module to compare the patient status to parameters corresponding to worsening heart failure indications to generate a notification of parameter violations.
