You probably will not be allowed to move your arm for at least 12 hours after the procedure. This will help prevent disturbing the lead and the device and let your chest heal. With epicardial pacemakers, the electrodes are attached to the surface of the heart rather than inside its chambers.
This is a surgical procedure done under general anesthesia. Your doctor will make a cut below your ribs or armpit to place the pacemaker. Epicardial pacemakers are used as a standard precaution during heart surgery. Wireless pacemakers are a newer type of pacemaker. The pulse generator and electrodes are all in one small device that is placed inside the heart.
A doctor will thread a tube called a catheter through a vein in your thigh up to your heart. The catheter moves the pacemaker using X-ray images to place it in a heart chamber. The procedure often takes less than an hour, and you may be able to leave the hospital the same day.
Typically, the recovery time is faster and the risk of infection is lower. The battery life of the device is between 8 and 13 years. After getting a permanent pacemaker, you will recover in the hospital for a few hours or overnight. Your healthcare team will tell you about any precautions or problems to watch out for during your recovery.
You will receive a card with information about the device and its settings, your doctor, and the hospital where you got it. Be sure to carry this card with you at all times. 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.
Your healthcare team may help you get up and walk around. The day after the procedure, you may get an X-ray to check that the pacemaker and wires stay in place. Your team may also suggest an electrocardiogram to look at your heart rhythm.
They will check to make sure the device is programmed correctly for you before you leave. They may also make sure the device can send data remotely. Your doctor will give you instructions to follow as you heal at home, such as:. The procedure to place a pacemaker is generally safe. However, complications can happen from the procedure or the pacemaker itself.
Talk with your doctor about the benefits and risks of a pacemaker. Complications may include:. A pacemaker can improve daily life for many people. Once you have a pacemaker, you will need regular doctor visits to check your health condition and the pacemaker.
Carry your pacemaker ID card with you for emergencies. Show it to airport security, new doctors, or other people who need to know about your device. You may need to visit your doctor several times a year to check your pacemaker.
In between visits, your doctor may be able to check that the battery and wires are still working. You may also need to come in if your doctor needs to reprogram the pacemaker.
You can check with your doctor regularly about device software updates and upgrades. If you have a pacemaker, avoid close or prolonged contact with electrical devices or devices that have strong magnetic fields.
These devices can disrupt the electrical signaling of your pacemaker and stop it from working properly. You may not be able to tell when this happens. To be safe, keep your pacemaker at least 6 inches away from such devices or only use them briefly, when needed. If something disrupts your pacemaker, step away from whatever is disturbing it to help your pacemaker return to normal.
Talk to your doctor right away about what else to avoid, as any kind of powerful electrical or industrial equipment can interfere with your pacemaker.
This includes welding machines or electric fences for pets. Medical and dental procedures that can affect your pacemaker include:. The effects depend on what type of device you have. Always tell your doctor or dentist that you have a pacemaker and show them the device ID card.
They may be able to make certain changes if you need the procedure or test. It is important to pay attention to any changes or unusual patterns in your pacemaker. Call your doctor if you think there is a problem. Learn more about participating in a clinical trial. View all trials from ClinicalTrials.

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? A pacemaker is implanted to help control your heartbeat. Your doctor may recommend a temporary pacemaker when you have a slow heartbeat bradycardia after a heart attack, surgery or medication overdose but your heartbeat is otherwise expected to recover.
A pacemaker may be implanted permanently to correct a chronic slow or irregular heartbeat or to help treat heart failure. The heart's natural pacemaker — the sinus node — produces electrical signals that prompt your heart to beat.
The heart is a muscular, fist-sized pump with four chambers, two on the left side and two on the right.
The upper chambers right and left atria and the lower chambers right and left ventricles work with your heart's electrical system to keep your heart beating at an appropriate rate — usually 60 to beats a minute for adults at rest. Your heart's electrical system controls your heartbeat, beginning in a group of cells at the top of the heart sinus node and spreading to the bottom, causing it to contract and pump blood. Aging, heart muscle damage from a heart attack, some medications and certain genetic conditions can cause an abnormal heart rhythm.
A pacemaker is a device used to control an abnormal heart rhythm. Depending on your condition, you may have a pacemaker with 1 to 3 flexible, insulated wires leads placed in one or more chambers of your heart.
These wires deliver the electrical pulses to adjust your heart rate. However, some newer pacemakers don't require leads. Pacemakers work only when needed. If your heartbeat is too slow bradycardia , the pacemaker sends electrical signals to your heart to correct the beat. Some newer pacemakers also have sensors that detect body motion or breathing rate and signal the devices to increase heart rate during exercise, as needed.
Complications related to pacemaker surgery or having a pacemaker are uncommon, but could include:. Before your doctor decides if you need a pacemaker, you'll have several tests done to find the cause of your irregular heartbeat. Tests done before you get a pacemaker could include:. You'll likely be awake during the surgery to implant the pacemaker, which typically takes a few hours. A specialist will insert an IV into your forearm or hand and give you a medication called a sedative to help you relax.
Your chest is cleaned with special soap. Most pacemaker implantations are done using local anesthesia to numb the area of the incisions. However, the amount of sedation needed for the procedure depends on your specific health conditions. You may be fully awake or lightly sedated, or you may be given general anesthesia fully asleep. One or more wires are inserted into a major vein under or near your collarbone and guided to your heart using X-ray images.
One end of each wire is secured at the appropriate position in your heart, while the other end is attached to the pulse generator, which is usually implanted under the skin beneath your collarbone.
A leadless pacemaker is smaller and typically requires a less invasive surgery to implant the device. The pulse generator and other pacemaker parts are contained in a single capsule. The doctor inserts a flexible sheath catheter in a vein in the groin and then guides the single component pacemaker through the catheter to the proper position in the heart.
You'll likely stay in the hospital for a day after having a pacemaker implanted. Your pacemaker will be programmed to fit your heart rhythm needs. You'll need to arrange to have someone drive you home from the hospital. Your doctor might recommend that you avoid vigorous exercise or heavy lifting for about a month.
Avoid putting pressure on the area where the pacemaker was implanted. In sick sinus syndrome, the SA node doesn't work as it should. This can lead to an abnormally slow heartbeat bradycardia , an abnormally fast heartbeat tachycardia , or a combination of both. Over time, the SA node tissue can become hardened and scarred. This can disrupt the normal pattern of electrical pulses released by the SA node. Some types of medication can also trigger sick sinus syndrome as a side effect.
These include calcium channel blockers and beta blockers. Atrial fibrillation is a condition that causes the heart to beat abnormally fast. Atrial fibrillation can usually be treated with medication, but some people don't respond to treatment, so a pacemaker may be recommended.
Sometimes people with atrial fibrillation can have a much slower pulse rate than normal, which can also be intermittent not continuous. In people with heart block , the pulse that needs to be sent from the SA node to the AV node is either delayed or absent.
Heart block can be caused when the heart is damaged acquired heart block , or it can occur if a baby is born with 1 or more defects that affect their heart congenital heart block. If you have heart block and it's causing troublesome symptoms, a pacemaker will usually be recommended. An implantable cardioverter defibrillator ICD , which is a device similar to a pacemaker, is mainly used to prevent cardiac arrest.
