A pacemaker is a device placed in your chest or abdomen that is programed to regulate an abnormal heartbeat which is called arrhythmia. Whether arrhythmia causes you to have a too slow, too fast, or irregular heartbeat, your pacemaker will monitor your heart rate and will help to normalize your heart beat when necessary. After implantation of your pacemaker, your physician will program your device with the specific strength and length of the impulses required, as well as speed of the pacemaker to correct any abnormalities you may experience with your heart rate. He or she will then regularly monitor your pacemaker’s data to review whether or not the device’s programming should be adjusted to better suit your needs or the battery needs replacing. Regular monitoring of your pacemaker can occur during visits to your doctor’s office or cardiac clinic, or you can choose to submit your pacemaker’s data remotely via telephone or internet.
