METHOD AND APPARATUS FOR DETERMINING THE CORONARY SINUS VEIN BRANCH ACCESSED BY A CORONARY SINUS LEAD
First Claim
1. A method for installing an electrode of a VRT device in a left ventricle of a patient'"'"'s heart, the method comprising:
- placing the electrode in a coronary sinus vein branch of the left ventricle;
detecting a plurality of electrical events in the patient'"'"'s heart during at least one heart beat, wherein at least one of the plurality of electrical events is sensed by the electrode; and
determining from the plurality of electrical events whether the electrode has an anterior or a lateral/posterior vein branch position during the heart beat; and
adjusting settings used by the VRT device based upon the determined position of the electrode.

Abstract
Systems and methods for determining the coronary sinus vein branch location of a left ventricle electrode are disclosed. The systems and methods involve detecting the occurrence of electrical events within the patient'"'"'s heart including sensing one or more of the electrical events with the electrode and then analyzing the electrical events to determine the electrode'"'"'s position. The determination of electrode position may be used to automatically adjust operating parameters of a VRT device. Furthermore, the determination of electrode position may be made in real-time during installation of the electrode and a visual indication of the electrode position may be provided on a display screen.
