Pacemaker for Heart Failure (Cardiac Resynchronization Therapy)
A pacemaker for heart failure, used for cardiac resynchronization therapy (CRT), sends electrical pulses to the heart to
keep the lower chambers (the ventricles) pumping together. This type of pacemaker is also called a biventricular pacemaker.
A doctor places the pacemaker in the chest. The pacemaker has three
wires, or leads, that connect to the heart through veins. One lead is in the right atrium (upper chamber). A second lead is in the right ventricle. The third lead is in a vein,
called the coronary sinus branch vessel, which is on the outside of the left ventricle.
