Abstract: System for arrhythmia detection and confirmation includes implantable medical device (IMD) having a sensing circuit for sensing cardiac activity (CA) for one or more cardiac cycles and generating one or more CA signals. An implantable pressure sensor (IPS) includes IPS sensing circuit for sensing pressure during the one or more cardiac cycles and generating one or more pressure signals. IMD and IPS include communications circuits for communicating with each other and/or an external device. One or both of IMD or IPS includes memory for storing program instructions and processor(s) for analyzing one of the CA or pressure signals, for one or more cardiac cycles, to detect a candidate arrhythmia. In response to detecting candidate arrhythmia, the processor(s) obtain another one of CA or pressure signals for cardiac cycles corresponding to the one or more cardiac cycles, and confirm or deny candidate arrhythmia based on the other one of the signals.

Abstract: A method for managing a treatment is provided. The method is under control of a processor. The method obtains a body generated analyte (BGA) indicative of a malnutrition state (MS) characteristic of interest (COI) of a patient and obtains implantable medical device (IMD) data indicative of a physiologic COI from the patient. The method assigns a health risk index based on the MS COI and the physiologic COI. The health risk index is indicative of a chronic disease state and malnutrition state currently exhibited by the patient. The method generates a treatment notification based on the health risk index.

Abstract: The present disclosure is directed to methods and systems for determining diuretic response profiles. The methods and systems include obtaining pulmonary artery pressure measurements from a patient prior to and after medication has been taken by the patient, comparing the pressures, and then determining the medication response profile in the patient. The methods and systems further include modifying the medication, withdrawing the medication, and/or identifying a non-responsive patient.
