ABSTRACT:
An endocardial apparatus for pacing four chambers of a heart, comprising: a power source housed in an implantable can, first, second and third leads having proximal and distal ends, each lead being electrically connected to the power source at its proximal end and extending into a vein proximal the heart, the first lead connecting at its distal end to an electrode that is in electrical contact with the right atrium of the heart, the second lead connecting at its distal end to an electrode that is in electrical contact with the right ventricle of the heart, the third lead connecting at a point proximal its distal end to a first electrode that is in electrical contact with the inside of the coronary sinus and oriented so as to stimulate the left atrium of the heart and connecting at its distal end to a second electrode that is in electrical contact with the inside of the great cardiac vein and oriented so as to stimulate the left ventricle of the heart. Devices are also disclosed for orienting and maintaining the position of the electrodes on the third lead.
