Claim One:
1. A method of diagnosis of heart failure, the method comprising: collecting, using an implantable device, a plurality of reference episodes; analyzing, using the implantable device, the plurality of reference episodes based on predefined criteria to assign each of the reference episodes an in-suspicion marker or an off-suspicion marker, wherein the in-suspicion marker indicates a suspicion that the reference episode is associated with cardiac decompensation, wherein the off-suspicion marker indicates a suspicion that the reference episode is not associated with cardiac decompensation; generating, using the implantable device, an in-suspicion model-cycle based on data associated with a plurality of in-suspicion reference episodes to which the in-suspicion marker has been assigned; generating, using the implantable device, an off-suspicion model-cycle based on data associated with a plurality of off-suspicion reference episodes to which the off-suspicion marker has been assigned; and determining, using the implantable device, whether to generate a heart failure alert based on a difference between the in-suspicion model-cycle and the off-suspicion model-cycle.
