Abstract
A method of diagnosing pulmonary congestion is provided. At least one decrease in a trans-thoracic impedance value from a baseline trans-thoracic impedance value is sensed. At least one increase in a heart rate value from a baseline heart rate value is also sensed. Pulmonary congestion is diagnosed if the decrease in the trans-thoracic impedance value corresponding to the increase in the heart rate does not increase after a predetermined interval. Systems and programs incorporating the method are also provided.
