Abstract:
1. A method comprising: selecting an electrode configuration from a plurality of electrode configurations associated with electrodes of an implantable lead wherein the electrode configuration comprises at least one right ventricular electrode and at least one left ventricular electrode; sensing activity of the right ventricle from the right ventricular electrode and the left ventricle from the left ventricular electrode; determining an interval between sensed activity of the right ventricle and sensed activity of the left ventricle; determining, based at least in part on the interval, whether the selected electrode configuration is suitable for delivery of cardiac resynchronization therapy wherein the determining comprises comparing the interval with a threshold value and determining whether the interval exceeds the threshold value; and switching to another electrode configuration only if the selected electrode configuration is not suitable for delivery of cardiac resynchronization therapy, otherwise using the selected electrode configuration for delivery of cardiac resynchronization therapy.
