ACTIVE IMPLANTABLE MEDICAL DEVICE COMPRISING MEANS FOR THE DIAGNOSIS OF HEART FAILURE
First Claim
1. A method of diagnosis of heart failure, the method comprising:
- collecting, using an implantable device, reference episodes, the reference episodes comprising, at least one of;
electrical activity signals of a myocardium;
myocardium hemodynamic activity signals, or indicators reflecting variation of physical parameters, variation of activity, and variation of hemodynamic phases between phases of effort and phases of recovery;
generating an in-suspicion model-cycle and an off-suspicion model-cycle based on the reference episodes; and
determining whether to generate an early heart failure alert, based on a difference between the in-suspicion model-cycle and the off-suspicion model-cycle.

Abstract
Methods, devices, and processor-readable storage media are provided for the diagnosis of heart failure. A method in this context includes collecting, using an implantable device, reference episodes, the reference episodes comprising, at least one of: electrical activity signals of a myocardium; myocardium hemodynamic activity signals, or indicators reflecting variation of physical parameters, variation of activity, and variation of hemodynamic phases between phases of effort and phases of recovery; generating an in-suspicion model-cycle and an off-suspicion model-cycle based on the reference episodes; and determining whether to generate an early heart failure alert, based on a difference between the in-suspicion model-cycle and the off-suspicion model-cycle.

20. A processor-readable, non-transitory storage medium having instructions stored thereon that, when executed by a processor, cause the processor to:
-
collect data relating to reference episodes, the reference episodes comprising, at least one of;
electrical activity signals of a myocardium;
myocardium hemodynamic activity signals, or indicators reflecting variation of physical parameters, variation of activity, and variation of hemodynamic phases between phases of effort and phases of recovery;generate an in-suspicion model-cycle and an off-suspicion model-cycle based on the reference episode data; and determine whether to generate an early heart failure alert, based on a difference between the in-suspicion model-cycle and the off-suspicion model-cycle.
