Abstract
An embodiment includes a main lead assembly having a proximal portion adapted for connection to a device and a distal portion adapted for placement in a coronary sinus, the distal portion terminating in a distal end for placement proximal a left ventricle. Additionally, the main lead assembly includes a left ventricular electrode located at its distal end which is adapted to deliver cardiac resynchronization therapy to reduce ventricular wall stress. The main lead assembly also includes a fat pad electrode disposed along the main lead assembly a distance from the distal end to position the fat pad electrode proximal to at least one parasympathetic ganglia located in a fat pad bounded by an inferior vena cava and a left atrium. The fat pad electrode is adapted to stimulate the parasympathetic ganglia to reduce ventricular wall stress.
