Embodiment Construction

[0044] Disclosed herein are systems, devices, and methods for detecting worsening cardiac conditions, including events indicative of worsening heart failure. WHF events may precede worsening systemic manifestations of HF. The systems, devices, and methods described herein can be used to determine the cardiac status of a patient and to track the progression of a cardiac condition, such as the progression of a HF event. The system may also be used in the setting of HF comorbidities and exacerbated chronic diseases such as pulmonary congestion, pneumonia or renal disease, among others.

[0045] figure 1 An example of a portion of the patient management system 100 and the environment in which the patient management system 100 may operate is generally shown. Patient management system 100 may include ambulatory system 105 associated with patient body 102 , external system 125 , and telemetry link 115 providing communication between ambulatory system 105 and external system 125 . ...

Abstract

Systems and methods for detecting worsening cardiac conditions such as worsening heart failure events are described. A system may include sensor circuits to sense physiological signals and signal processors to generate from the physiological signals first and second signal metrics. The system may include a risk stratifier circuit to produce a cardiac risk indication. The system may use at least the first signal metric to generate a primary detection indication, and use at least the second signal metric and the risk indication to generate a secondary detection indication. The risk indication may be used to modulate the second signal metric. A detector circuit may detect the worsening cardiac event using the primary and secondary detection indications.

Description

[0001] priority claim [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 62 / 316,905, filed April 1, 2016, which is incorporated herein by reference in its entirety. technical field [0003] This document relates generally to medical devices, and more particularly to systems, devices, and methods for detecting and monitoring events indicative of exacerbation of congestive heart failure. Background technique [0004] Congestive heart failure (CHF or HF) is a major health problem and affects many people in the United States alone. CHF patients may have an enlarged heart with weakened heart muscles, resulting in poor blood output from the heart. Although CHF is usually a chronic disease, it can occur suddenly. It can affect the left heart, right heart, or both sides of the heart. If CHF affects the left ventricle, the signals that control the contraction of the left ventricle are delayed, and the ...
