SYSTEMS AND METHODS FOR CONFIGURATION OF ATRIOVENTRICULAR INTERVAL

摘要

Systems and methods are described herein for assisting a user in identification and/or optimization of an atrioventricular (A-V) interval for use in cardiac therapy. The systems and methods may monitor electrical activity of a patient using external electrode apparatus to provide electrical heterogeneity information for a plurality of different A-V intervals and may identify an A-V interval based on the electrical heterogeneity information.

1. A system for use in cardiac therapy comprising:
electrode apparatus comprising a plurality of external electrodes configured to be located proximate tissue of a patient; and computing apparatus coupled to the electrode apparatus and configured to:
initiate delivery of left ventricular pacing therapy at a plurality of different A-V intervals, wherein the left ventricular pacing therapy is delivered using at least one pacing electrode configured to pace the patient's left ventricle and without any sensing electrodes located in the patient's right ventricle,monitor electrical activity using the plurality of external electrodes during the delivery of left ventricular pacing therapy,generate electrical heterogeneity information representative of at least one of mechanical cardiac functionality and electrical cardiac functionality for each of the plurality of different A-V intervals based on the monitored electrical activity, andidentify an A-V interval from the plurality of different A-V intervals based on the electrical heterogeneity information.
