Embodiment Construction

[0042] Disclosed herein are systems, devices, and methods for assessing the adverse hemodynamic effects of an atrial tachyarrhythmia, such as an atrial fibrillation (AF) episode. By monitoring a patient's hemodynamic sensor response to one of multiple candidate AF therapies, such as using a heart sound sensor, the systems and methods discussed herein can provide information for end-user diagnostics including categorical hemodynamic stability during AF . The systems and methods discussed herein can also be used to assess the hemodynamic effects of other atrial tachyarrhythmias, such as atrial tachycardia or atrial flutter.

[0043] figure 1 An example of a cardiac rhythm management (CRM) system 100 and a portion of an environment in which the CRM system 100 may operate is shown. The CRM system 100 may include a dynamic medical device (such as an implantable medical device (IMD)) 110 (which may be electrically coupled to the heart 105, for example, by one or more leads 108A-10...

Abstract

Systems and methods for assessing hemodynamic status of a patient experiencing atrial tachyarrhythmia such as an atrial fibrillation (AF) episode are disclosed. A system can comprise an atrial tachyarrhythmia detection circuit configured to detect an AF episode, a hemodynamic sensor circuit configured to sense at least one hemodynamic signal, and a hemodynamic status analyzer circuit that can calculate one or more signal metrics using the sensed hemodynamic signal during the AF episode. The hemodynamic status analyzer circuit can categorize the hemodynamic status of the patient into one of two or more categorical hemodynamic status levels which indicate elevated hemodynamic impact of the detected AF episode. A user interface can provide to an end-user a presentation of the categorized hemodynamic status level during AF.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 62 / 006,595, filed June 2, 2014, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to medical devices and, more particularly, to systems, devices and methods for assessing hemodynamic status during an atrial tachyarrhythmia such as atrial fibrillation. Background technique [0004] Atrial fibrillation (AF) is the most common clinical cardiac arrhythmia and accounts for approximately one-third of admissions due to the arrhythmia. An estimated 2.3 million people in North America have AF. During AF, the normal regular sinus rhythm is overwhelmed by chaotic electrical impulses originating in or near the atria. This can lead to irregular conduction to the ventricles, causing an inappropriately fast and irregular heart rate. One t...
