Techniques for Correlating Thoracic Impedance with Physiological Status

摘要

Exemplary techniques for correlating thoracic impedance values with physiological status are described. One technique involves an implantable medical device (IMD) that includes means for correlating thoracic impedance values with a patient's physiological status and means for interpreting the correlated thoracic impedance values utilizing a patient-based threshold to detect a heart failure condition.
