A pacemaker is any device that sends controlled electrical impulses to certain areas of the heart in order to stimulate cardiac contraction when the heart’s intrinsic electrical system is not functioning normally. The overall purpose of pacemakers is to restore normal electrical activity, improve heart function, and regulate cardiac pacing as part of cardiac resynchronization therapy (CRT).

Based on current guidelines, approximately 40% of patients with systolic heart failure are cardiac resynchronization therapy candidates. For patients with heart failure[1], myocardial dysfunction, and prolonged ventricular depolarization on a surface electrocardiogram (ECG), CRT has been proven effective.
