How do pacemakers help

You should not do any lifting or pulling on anything for a few weeks. You may be instructed to limit movement of the arm on the side that the pacemaker was placed, based on your doctor's preferences. You will most likely be able to resume your usual diet, unless your doctor instructs you differently. It will be important to keep the insertion site clean and dry. You will be given instructions about bathing and showering. Ask your doctor when you will be able to return to work. The nature of your occupation, your overall health status, and your progress will determine how soon you may return to work.

Increased pain, redness, swelling, or bleeding or other drainage from the insertion site. Your doctor may give you additional or alternate instructions after the procedure, depending on your particular situation. The following precautions should always be considered. Discuss the following in detail with your doctor, or call the company that made your device:.

Always carry an ID card that states you have a pacemaker. In addition, you may want to wear a medical identification bracelet indicating that you have a pacemaker.

Let screeners know you have a pacemaker before going through airport security detectors. In general airport detectors are safe for pacemakers, but the small amount of metal in the pacemaker and leads may set off the alarm. If you are selected for additional screening by hand-held detector devices, politely remind the screeners that the detector wand should not be held over your pacemaker for longer than a few seconds, as these devices contain magnets and thus may affect the function or programming of your pacemaker.

You may not have a magnetic resonance imaging MRI procedure unless you have a specially designed pacemaker. You should also avoid large magnetic fields such as power generation sites and industrial sites such as automobile junkyards that use large magnets.

Turn off large motors, such as cars or boats, when working close to them as they may create a magnetic field. Avoid high-voltage or radar machinery, such as radio or television transmitters, electric arc welders, high-tension wires, radar installations, or smelting furnaces.

If you are having a surgical procedure performed, inform your surgeon that you have a pacemaker well before the operation. Also ask your cardiologist's advice on whether anything special should be done prior to and during the surgery, as the electrocautery device that controls bleeding may interfere with the pacemaker. Sometimes the pacemaker's programming will be temporarily changed using a magnet during the surgery to minimize the possibility of interference from the electrocautery.

When involved in a physical, recreational, or sporting activity, protect yourself from trauma to the pacemaker. A blow to the chest near the pacemaker can affect its functioning.

If you are hit in that area, you may want to see your doctor. Cell phones in the U. Avoid carrying a cell phone in your breast pocket over your pacemaker. Always consult your doctor when you feel ill after an activity, or when you have questions about beginning a new activity.

Always consult your doctor if you have any questions concerning the use of certain equipment near your pacemaker. Health Home Treatments, Tests and Therapies. The heart's electrical system The heart is basically a pump made up of muscle tissue that is stimulated by electrical currents, which normally follow a specific circuit within the heart. What is a pacemaker?

Reasons for the procedure A pacemaker may be inserted in order to stimulate a faster heart rate when the heart is beating too slowly, and causing problems that cannot otherwise be corrected. Some examples of heart rate and rhythm problems for which a pacemaker might be inserted include: Bradycardia. This occurs when the sinus node causes the heart to beat too slowly. Tachy-brady syndrome. This is characterized by alternating fast and slow heartbeats.

There may be other reasons for your doctor to recommend a pacemaker insertion. Risks of the procedure Possible risks of pacemaker include, but are not limited to, the following: Bleeding from the incision or catheter insertion site Damage to the vessel at the catheter insertion site Infection of the incision or catheter site Pneumothorax.

Patients who are allergic to or sensitive to medications or latex should notify their doctor. Because most of today's pacemakers automatically adjust the heart rate to match the level of physical activity, they may can allow you to resume a more active lifestyle. Your doctor should check your pacemaker every 3 to 6 months. Tell your doctor if you gain weight, if your legs or ankles get puffy, or if you faint or get dizzy. Most pacemakers can be checked by your doctor remotely, which means you don't have to go into the doctor's office.

Your pacemaker sends information to your doctor, including your heart rate and rhythm, how your pacemaker is working, and how much battery life is left.

Your pacemaker's battery should last 5 to 15 years. When the battery stops working, you'll need surgery to replace it. The procedure to change your pacemaker's battery is often quicker and requires less recovery time than the procedure to implant your pacemaker.

If you have a pacemaker and become terminally ill with a condition unrelated to your heart, such as cancer, it's possible that your pacemaker could prolong your life. Doctors and researchers vary in their opinions about turning off a pacemaker in end-of-life situations.

Talk to your doctor if you have a pacemaker and are concerned about turning it off. You may also want to talk to family members or another person designated to make medical decisions for you about what you'd like to do in end-of-life care situations.

How Pacemakers Work - Pacemakers. Traditional transvenous pacemakers Traditional pacemakers also called transvenous pacemakers have three main parts. A pulse generator creates the electrical pulses. Wires also called leads are implanted inside the veins and carry the pulses to your heart. Electrodes sense your natural heartbeat.

When your heartbeat is slower than normal, the electrodes deliver electrical impulses to your heart to make it beat normally. The image shows a cross-section of a chest and heart with a traditional pacemaker, which has wires leads. Figure A shows a double-lead pacemaker also called a double-chamber pacemaker in the upper chest. Figure B shows an electrode using electrical signals to activate the heart muscle.

Figure C shows a single lead pacemaker also called a single-chamber pacemaker in the upper chest. Wireless pacemakers not pictured are placed inside the right ventricle. Wireless pacemakers Wireless, or leadless, pacemakers are smaller than traditional types about the size of a large pill capsule.

Other types In another type of pacemaker, the electrodes are placed on the surface of your heart rather than inside your heart. Who Needs a Pacemaker? Before Getting a Pacemaker - Pacemakers.

You can bring along these and other questions you may have: What are the benefits and risks of a pacemaker? What other treatment options do I have? How will a pacemaker affect my life? What kind of pacemaker is best for me? What happens during the procedure? How long will the pacemaker last? When should I stop eating or drinking before the procedure? Should I continue taking my regular medicines?

When should I arrive at the hospital and where should I go? How long should I expect to stay at the hospital? How long will my recovery be? Will I be sore or not able to move? What medicines should I take after the procedure? How Is a Pacemaker Placed?

Wired transvenous pacemakers Many traditional, and all temporary, pacemakers are transvenous pacemakers, meaning the wires and electrodes are threaded through your veins. Epicardial pacemakers With epicardial pacemakers, the electrodes are attached to the surface of the heart rather than inside its chambers.

They may also be used: When a vein is blocked by a blood clot or plaque When it would be difficult to insert the wires inside your heart chamber because of the structure of your heart or veins When they are needed by newborns or children, who are the most common users If you have a heart infection Wireless pacemakers Wireless pacemakers are a newer type of pacemaker. After Getting a Pacemaker - Pacemakers. Recovery at the hospital If you have a permanent pacemaker, you may have to stay in the hospital overnight so your healthcare team can check your heartbeat and make sure your device is working well.

Recovery at home Your doctor will give you instructions to follow as you heal at home, such as: What medicines to take When to return to normal activities. Your doctor will probably ask you to avoid driving or heavy lifting for at least a week. Most people return to other daily activities within a few days of having surgery. How to prevent wires from moving.

Your doctor may ask you to use caution or avoid heavy lifting, intense physical activity, or lifting your arms above your head. These activities could shift the device or a wire out of place.

When to make a follow-up appointment. Typically, the first appointment is one month after implant, with follow-up visits every 6 to 12 months. Possible complications from a pacemaker The procedure to place a pacemaker is generally safe. Complications may include: Allergic reaction to the device or medicines used during the procedure Blood clots that block blood flow.

You may be advised not to:. When you leave the hospital, you will be given a card to keep in your wallet. This card lists the details of your pacemaker and has contact information for emergencies.

You should always carry this wallet card with you. You should try to remember the name of the pacemaker manufacturer if you can in case you lose your card. Pacemakers can help keep your heart rhythm and heart rate at a safe level for you. The pacemaker battery lasts about 6 to 15 years. Your provider will check the battery regularly and replace it when necessary.
