Method and apparatus for determining the coronary sinus vein branch accessed by a coronary sinus lead
First Claim
1. A method for determining a position of a first electrode placed within a left ventricle area of a heart, the method comprising the steps of:
- detecting a first depolarization event within the heart;
sensing, with the first electrode, a second depolarization event within the heart;
measuring a first interval between the first depolarization event and the second depolarization event; and
determining from at least the first interval whether the first electrode has a lateral/posterior position or an anterior position within the left ventricle.

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.
