Pacemakers are set by the surgeon-physician at the time it is implanted. Most times, the pacemaker is simply set to a normal heart rate (around 70-80 beats per minute). The primary function of the pacemaker is to restore a more regular beat when the heart cannot maintain a normal heart rate. You should consult your physician-surgeon for particulars about your pacemaker, its use, function, and signs/symptoms to watch for after the pacemaker is implanted.
