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.

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. Your doctor may give you blood thinners to reduce this risk. If it senses dangerous rhythms, it delivers shocks. This treatment is called defibrillation.
Most new ICDs can act as both a pacemaker and a defibrillator. Many ICDs also record the heart's electrical patterns when there is an abnormal heartbeat.
This can help the doctor plan future treatment. Getting a pacemaker or ICD requires minor surgery. You usually need to stay in the hospital for a day or two, so your doctor can make sure that the device is working well. You will probably be back to your normal activities within a few days. The information on this site should not be used as a substitute for professional medical care or advice. There are several types of pacemaker available.
Together with your doctor, ask about the options and talk about what may work best for you. The entire procedure usually takes about one hour, although this can vary. You may experience some discomfort and bruising around your pacemaker site, but serious complications from pacemakers are very unusual.
You will need an assessment by a specialist to check on your condition before you return to driving. Over four to six weeks following the procedure, you will be able to slowly build up to your normal living activities. It takes a few weeks for the pacemaker wires to become fully secure and for the discomfort to go away. After two weeks you will be allowed to drive again. After four to six weeks you will be able to start lifting heavier items and lifting your arm above shoulder-height.
After getting a pacemaker you will be given an ID card for your pacemaker. It's important to carry this with you at all times, along with a list of your medications. Be prepared to show your ID card if you need to walk through a metal detector for example, at an airport.
A pacemaker allows your heart to maintain an adequate heart rate which in turn allows a normal, healthy blood flow throughout your body. There are a few reasons your physician may recommend an ICD as the best course of treatment. It is likely you are at a very high risk for a malignant ventricular arrhythmia, i. While a pacemaker is used to speed up your heart rate back to normal if it skips a beat or slows down, an ICD is capable not only of all pacemaker functions, but also of delivering a shock to reset too fast, deadly, heart rates thus restoring normal blood flow to your body.
Ventricular Tachycardia VT or V-tach — A typical normal heartbeat at rest is considered to be 50 to 90 beats per minute. When experiencing V-tach, your heart will beat very fast, sometimes even reaching heart rates above times per minute. Although it cannot prevent V-tach from occurring, an ICD can stop it. Your electrophysiologist can discuss options to lower the chance of V-tach from occurring, but due to medication and procedures being incapable of completely eliminating the risk of V-tach, an ICD is necessary to provide protection.
After recovering from the procedure, your life may change, but only slightly. Your care team will give you strict guidelines to follow to ensure you have the best recovery possible.
