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.
Claims73
A method of diagnosing pulmonary congestion, comprising:
- sensing at least one decrease in a trans-thoracic impedance value from a baseline trans-thoracic impedance value;
- sensing at least one increase in a heart rate value from a baseline heart rate value;
- and
- diagnosing pulmonary congestion if the decrease in the trans-thoracic impedance value corresponding to the increase in the heart rate does not increase after a predetermined interval.
An implantable medical device comprising:
- a processor;
- at least one impedance sensor operably connected to the processor, wherein
- the sensor senses at least one decrease in a trans-thoracic impedance value from a baseline trans-thoracic impedance value, the trans-thoracic impedance value corresponding to an increase in heart rate and the processor diagnoses pulmonary congestion if the decrease in the trans-thoracic impedance value does not increase after a predetermined interval.
An implantable medical system, comprising:
- means for sensing at least one decrease in a trans-thoracic impedance value from a baseline trans-thoracic impedance value;
- means for sensing at least one increase in a heart rate value from a baseline heart rate value;
- and
- means for diagnosing pulmonary congestion if the decrease in the trans-thoracic impedance value corresponding to the increase in the heart rate does not increase after a predetermined interval.
A computer usable medium including a program for diagnosing pulmonary congestion, comprising:
- computer program code that senses at least one decrease in a trans-thoracic impedance value from a baseline trans-thoracic impedance value;
- computer program code that senses at least one increase in a heart rate value from a baseline heart rate value;
- and
- computer program code that diagnoses pulmonary congestion if the decrease in the trans-thoracic impedance value corresponding to the increase in the heart rate does not increase after a predetermined interval.
