Abstract:
1. A method for use with an implantable medical device for implant within a patient, the method comprising: detecting values representative of right ventricular (RV) stroke volume within the patient using at least one of a sensor and electrodes; detecting values representative of left ventricular (LV) stroke volume within the patient using at least one of the sensor and electrodes; evaluating differences, utilizing one or more microcontrollers, between the RV stroke volume values and the LV stroke volume values wherein the evaluating differences include calculating an accumulated difference between the RV stroke volume values and the LV stroke volume values; and detecting, utilizing the one or more microcontrollers, an indication of pulmonary congestion based on a comparison between an accumulation threshold and the accumulated difference between the RV stroke volume values and the LV stroke volume values.
