Abstract

A cardiac rhythm management system that senses a cardiac signal indicative of a heartbeat and an acoustic signal indicative of a heart sound, and detects atrial tachyarrhythmias based on the sensed cardiac and acoustic signals. In various embodiments, the present system senses cardiac and acoustic signals without the use of atrial leads, thus allowing, for example, monitoring of atrial fibrillation burden in heart failure patients not wearing implantable devices with atrial leads . In various embodiments, the system detects heartbeats and sounds, measures parameters associated with the detected heartbeats and sounds, and uses the measured parameters to detect one or more specified types of atrial tachyarrhythmias. In various embodiments, the measured parameter is selected from heart rate, heart sound amplitude, cycle length variability, and systolic and diastolic intervals.

Description

[0001] priority statement [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Serial No. 62 / 006,446, filed June 2, 2014, which is hereby incorporated by reference in its entirety. [0003] Cross References to Related Applications [0004] This application is related to co-pending, commonly assigned Provisional U.S. Patent Application No. 62 / 004,481, entitled "SYSTEM AND METHODS FOR DETECTING ATRIALTACHYARRHYTHMIA USING HEMODYNAMIC SENSORS," filed May 29, 2014, which is incorporated by reference in its entirety to In this article. technical field [0005] This document relates generally to cardiac rhythm management, and in particular to the use of a patient's heart rate and heart sounds to detect atrial tachyarrhythmias. Background technique [0006] The heart is the center of the human circulatory system. It includes an electromechanical system that performs two main pumping functions. The left side of the heart draws ...
