International Classification:

A61B 5/0402

US Classification:

600515, 600509, 600518

Abstract:

A CRM system enhances intracardiac electrogram-based arrhythmia detection using a wireless electrocardiogram (ECG), which is a signal sensed with implantable electrodes and approximating a surface ECG. In one embodiment, an intracardiac electrogram allows for detection of an arrhythmia, and the wireless ECG allows for classification of the detected arrhythmia by locating its origin. In another embodiment, the wireless ECG is sensed as a substitute signal for the intracardiac electrogram when the sensing of the intracardiac electrogram becomes unreliable. In another embodiment, a cardiac signal needed for a particular purpose is selected from one or more intracardiac electrograms and one or more wireless ECGs based on a desirable signal quality. In another embodiment, intracardiac electrogram-based arrhythmia detection and wireless ECG-based arrhythmia detection confirm with each other before indicating a detection of arrhythmia of a certain type.

Appl. No.:

Inventors:

Valerie Smith - Mahtomedi MN, US
Julie Thompson - Circle Pines MN, US

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61N 1/362

US Classification:

607 28, 607 9, 607 14

Abstract:

This document discusses, among other things, systems, devices, and methods for detecting or classifying tachyarrhythmias or making a therapy decision. In one example, a rate-dependent threshold is used for comparing atrial and ventricular rates for classifying a tachyarrhythmia as a ventricular tachyarrhythmia (VT) or a supraventricular tachyarrhythmia (SVT). In another example, the classification uses an atrial rate cutoff value, a ventricular rate cutoff value, or both. In another example, a tachyarrhythmia detection is tested over a time window with a duration that is automatically adjusted as a substantially continuously monotonically decreasing function of duration vs. rate. These techniques improve the specificity of arrhythmia detection or classification, allow anti-tachyarrhythmia therapy to be better tailored to the particular tachyarrhythmia, or provide more automatic operation making it easier for a physician to use an implantable device.

US Classification:

600518, 600515

Abstract:

This document discusses, among other things, a method of identifying a non-fatal tachyarrhythmia episode by determining a degree of similarity between the episode and a template generated from a previous tachyarrhythmia episode.

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61B 5/04

US Classification:

600515, 600518

Abstract:

An implantable medical device senses a plurality of electrograms from substantially different atrial locations, detects regional depolarizations from the electrograms, and analyzes timing relationships among the regional depolarizations. The timing relationships provide a basis for effective therapy control and/or prognosis of certain cardiac disorders. In one embodiment, an atrial activation sequence is mapped to show the order of occurrences of the regional depolarizations during an atrial depolarization for classifying a detected tachyarrhythmia by its origin. In another embodiment, conduction time between two atrial locations is measured for monitoring the development of an abnormal atrial conditions and/or the effect of a therapy.

Appl. No.:

10/844475

Inventors:

Julie Thompson - Circle Pines MN, US

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61B 5/0452
A61B 5/0464
A61B 5/0468

US Classification:

600518, 600516

Abstract:

An implantable cardioverter/defibrillator includes a tachycardia detection system that detects one-to-one (1:1) tachycardia, which is a tachycardia with a one-to-one relationship between atrial and ventricular contractions. When the 1:1 tachycardia is detected, the system discriminates ventricular tachycardia (VT) from supraventricular tachycardia (SVT) based on analysis of a cardiac time interval. Examples of the cardiac time interval include an atrioventricular interval (AVI) and a ventriculoatrial interval (VAI). A template time interval is created during a known normal sinus rhythm. The system measures a tachycardia time interval after detecting the 1:1 tachycardia, and indicates a VT detection if the tachycardia time interval differs from the template time interval by at least a predetermined percentage of the template time interval.

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61B 5/04

US Classification:

600509, 600513, 600515

Abstract:

Systems, devices, and methods detect or classify tachyarrhythmias or make a therapy decision. A tachyarrhythmia can be classified using a rhythm discrimination parameter having a value. In certain examples, the value of the rhythm discrimination parameter can be adjusted using a relationship between a detected atrial rate and a detected ventricular rate, or the value can be adjusted using information about at least one of the atrial rate or the ventricular rate in addition to using the relationship between the atrial rate and the ventricular rate. These techniques can improve the specificity of arrhythmia detection or classification, allow anti-tachyarrhythmia therapy to be better tailored to the particular tachyarrhythmia, or provide more automatic operation making it easier for a physician to use an implantable device.
