Devices, systems, and methods for characterizing a tachycardia and/or selecting treatment for a tachycardia using results of a dominant frequency analysis

摘要

Provided herein are implantable systems, and methods for use therewith, for characterizing a tachycardia and/or selecting treatment for a tachycardia using results of a dominant frequency analysis. One or more electrogram (EGM) signal(s) indicative of cardiac electrical activity are obtained. For at least one of the EGM signal(s) a dominant frequency (DF) analysis is performed, and the results of the DF analysis are used to characterize a tachycardia and/or to select treatment for a tachycardia.

主权项

1. A method for use with an implantable system, comprising:
(a) obtaining one or more electrogram (EGM) signal(s) indicative of cardiac electrical activity; (b) performing dominant frequency (DF) analysis of at least one of the EGM signal(s), wherein DF analysis comprises determining the DF of at least one of the EGM signal(s) in the frequency domain, wherein the DF is the frequency component of the EGM signal in the frequency domain having the greatest amplitude; and (c) using results of the DF analysis to determine whether to deliver anti-tachycardia pacing (ATP) to attempt to terminate a tachycardia, or whether to deliver a shock to attempt to terminate the tachycardia without first delivering ATP.
