Pacemaker

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

Activity Guidelines

  • Driving is allowed after one to six weeks. You will be given instructions about driving at your one-week follow-up appointment.
  • Exercise is encouraged. It is important to start slowly and progress gradually. You can check your heart rate by taking your pulse before and after exercise. Be sure to rest when you are tired. There are many benefits to a regular exercise program. Talk with your doctor to see what options are best for you.
  • Avoid exercise or activity that could result in blunt blows to the pacemaker site, such as contact sports.
  • Avoid lifting objects over 10 pounds (groceries, laundry, children, etc.) until six weeks after surgery.
  • Avoid activity involving stretching and/or reaching movements with your affected arm for six weeks after your surgery (such as golf or tennis).
  • Avoid swimming for six weeks until the incision is completely healed, to decrease the risk of infections.
  • Avoid dental work for three months after implant.

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.

Follow-up Care

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.
