Embodiment Construction

[0020] Disclosed herein are systems, devices, and methods for automatically generating differential diagnosis decisions for HF deterioration, such as HF decompensation. The differential diagnosis decision may include a diagnostic score (each associated with a corresponding candidate condition such as HF worsening event, lung disease, atrial or ventricular arrhythmia, indication of surgery, or infection). The diagnostic score associated with a specific candidate condition can be generated using physiological signals or other physiological information obtained from the patient. The diagnostic score indicates the likelihood of pathophysiological manifestations (e.g., deteriorating patient state) caused by the candidate condition. The automatically generated differential diagnosis can be shown to end users in guiding patient treatment and management decisions.

Abstract

Devices and methods for differentially diagnosing between worsening heart failure (HF) and other diseases or medical conditions are described. A medical system can receive patient information including one or more physiologic signals, and detect a respective physiologic feature from each of the one or more received physiologic signals. The medical system can include a differential diagnosis circuit that generates one or more signal metrics, receive two or more candidate conditions associated with the change in patient physical or physiological status, and determine a respective diagnostic score for each of the candidate conditions. The diagnostic score can indicate likelihood the change in the patient physical or physiologic status being caused by the corresponding candidate condition. A user interface can be provided to generate a presentation of the detected physiologic features and the diagnostic scores associated with the candidate conditions.

Description

[0001] Cross references to related applications [0002] This application claims the right of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 61 / 993,824 filed on May 15, 2014, the entire content of which is incorporated herein by reference. Technical field [0003] The present invention relates generally to medical devices, and more specifically, to systems, devices, and methods for detecting and monitoring heart failure decompensation. Background technique [0004] Congestive heart failure (CHF) is a major health problem and affects more than five million people in the United States alone. CHF is a loss of pumping energy of the heart, resulting in an inability to deliver enough blood to meet the needs of surrounding tissues. CHF patients usually have an enlarged heart due to a weakened heart muscle, resulting in reduced contractility and poor cardiac blood output. [0005] CHF is usually chronic, but it can happen suddenly. It can affect the left...
