A pacemaker is a device that can protect you against certain abnormal heart rhythms by constantly monitoring your heart. The pacemaker is able to detect a slow heart rhythm (bradycardia) and produce electrical impulses to increase your heart rate. If your heartbeat is too slow, there is not enough blood pumped to meet your body's needs. This may make you feel tired, weak, lightheaded or short of breath. A pacemaker restores the proper heart rate and rhythm.
Usually the pacemaker is implanted in the upper chest area just below the collarbone. The pacemaker is very small in size; most weigh an ounce or less. The pacemaker consists of a pulse generator (a battery and an electrical circuit) and a lead wire. The wire, or pacing lead, is threaded through a vein leading to the heart. The lead carries information about your heart rhythm back to the generator. It also is used to transmit needed electrical impulses to the heart. The leads and the generator are connected after proper placement is confirmed. The doctor will program the pacemaker to best fit your specific needs.
The pacemaker placement takes about two hours and is done in the Electrophysiology (EP) Lab.
Life with Your Pacemaker
Magnets and Electrical Devices
Normal use of properly operating household appliances will not damage your pacemaker. Using electric arc welders or working on automobile ignition systems will also not damage your pacemaker but they can interfere with the pacemaker function. If you are using electrical equipment or working around running motors and you become lightheaded or feel palpitations, turn the equipment off or walk away from it. Normal pacemaker function should resume.
It is important to notify all of your doctors that you have a pacemaker. If there are any questions concerning specific tests, we can provide you with further information.
After your pacemaker is implanted, you will be followed closely by your doctor to assure that it is working properly. Your follow-up care will be managed through the pacemaker clinic. The pacemaker may be re-programmed to fit your needs; examining and adjusting the pacemaker is quick and painless. Your pacemaker will last up to 10 years (this varies according to how often it is used and how it is programmed). Part of your follow-up involves checking the battery life of your device. It is very important that you keep your appointments.
