Embodiment Construction

[0023] In the following description, reference is made to illustrative examples for practicing the methods described herein. It is understood that other embodiments may be used without departing from the scope of the present disclosure.

[0024] In various examples, cardiac electrical signals are used to determine continuous ventricular cycle lengths for detection of atrial arrhythmias. The ventricular cycle length can be determined as the interval between successive R-waves sensed from the electrical signal of the heart and accompanied by ventricular depolarization. Differences between consecutive RR intervals (RRI) are analyzed for evidence of atrial tachyarrhythmias (eg, atrial fibrillation). As described herein, periods of cardiac signal can be classified as AF, non-AF, or unclassified based on analysis of RRI and other factors. A medical device operating in accordance with the techniques disclosed herein may detect AF when a predetermined number of time periods of a car...

Abstract

A medical device (60) for detecting an atrial tachyarrhythmia comprises a processor configured to determine RR intervals between successive R-waves of a cardiac electrical signal and to determine classification factors from the R-waves identified over a predetermined time period by determining at least a first classification factor correlated to variability of the RR intervals and a second classification factor indicating a presence of a ventricular tachyarrhythmia. The processor is configured to classify the cardiac electrical signal of the predetermined time period as unclassified, atrial tachyarrhythmia or non-atrial tachyarrhythmia based on a comparison of the determined classification factors to classification criteria.

Description

technical field [0001] The present disclosure relates generally to cardiac medical devices, and in particular to cardiac medical devices and methods for detecting the onset of atrial arrhythmia from sensed cardiac electrical signals. Background technique [0002] During normal sinus rhythm (NSR), the heartbeat is regulated by electrical signals generated by the sinoatrial (SA) node located in the wall of the right atrium. Each atrial depolarization signal generated by the SA node propagates across the atria (causing depolarization and contraction of the atria) and reaches the atrioventricular (A-V) node. The A-V node responds by propagating ventricular depolarizing signals through the His bundle of the ventricular septum and subsequently to the bundle branches and Purkinje myofibers of the right and left ventricles. [0003] Atrial tachyarrhythmias include unorganized forms of atrial fibrillation and various degrees of organized atrial tachycardia, including atrial flutter....
