Patent ID: 7127290

Claim:
A cardiac rhythm management system comprising: an implantable cardiac rhythm management device comprising: at least one congestive heart failure (CHF) physiologic parameter input device to provide CHF physiologic information about a subject, the CHF physiologic information comprising information about at least one of the subject's dyspnea, orthopnea, neck vein distension, abdominojugular reflex, cough, hepatomegaly, peripheral edema, brain patriaretic peptide (BNP) level, or at least one of pulmonary edema, cardiomegaly, or pleural effusion wherein the input device comprises an implantable transthoracic impedance sensor configured to provide information about the subject's pulmonary edema, cardiomegaly, or pleural effusion; and a processor circuit, comprising at least one processor input coupled to the at least one CHF physiologic parameter input device to receive a plurality of different CHF physiologic parameters, the processor comprising: weighting factors, stored in a memory, the weighting factors corresponding to each of the received CHF physiologic parameters; and a CHF status change probability indicator, to predict a likelihood of a subsequent change in a CHF status of a subject using the plurality of different received CHF physiologic parameters and corresponding weighting factors; and an external remote user interface communicatively couplable to the implantable cardiac rhythm management device, the external remote user interface comprising a user-detectable indication of the CHF status change probability indicator received from the implantable cardiac rhythm management device, in which the remote user interface comprises a user input device to receive at least one CHF physiologic parameter from a user and to communicate to the at least one CHF physiological parameter input device in the implantable cardiac rhythm management device the at least one CHF physiological parameter selected from the group consisting of at least one or more of the subject's dyspnea, orthopnea, neck vein distension, abdominojugular reflex, cough, hepatomegaly, peripheral edema, brain natriaretic peptide (BNP) level, pulmonary edema, cardiomegaly, or pleural effusion.
