Pacemaker
FAQS
Why Do I Need A Pacemaker?
If the electrical pathway is interrupted for any reason, changes in the heart rate and rhythm occur that make a pacemaker necessary.
What Happens Before The Procedure?
Before the procedure begins, a nurse will help you get ready. You will lie on a bed, and the nurse will start an IV in a vein in your arm or hand.
To prevent infection and to keep the pacemaker insertion site sterile:
- An antibiotic will be given through the IV at the beginning of the procedure
- The left or right side of your chest will be shaved
- A special soap will be used to cleanse the area
- Sterile drapes are used to cover you from your neck to your feet
- A soft strap will be placed across your waist and arms to prevent your hands from coming in contact with the sterile area
Will I Be Awake?
Yes. A medication will be given through your IV to relax you and make you feel drowsy, but you will not be asleep during the procedure.
Where Is The Pacemaker Implanted?
A pacemaker can be implanted using the endocardial or epicardial approach.
The endocardial (transvenous) approach is the most common method. A local anesthetic is given to numb the area. An incision is made in the chest where the leads and pacemaker are inserted. The lead(s) is inserted through the incision and into a vein, then guided to the heart with the aid of the fluoroscopy machine. The lead tip attaches to the heart muscle, while the other end of the lead (attached to the pulse generator) is placed in a pocket created under the skin in the upper chest.
The epicardial approach is a less common method in adults, but more common in children. During this surgical procedure, general anesthesia is given to put you to sleep. The surgeon attaches the lead tip to the heart muscle, while the other end of the lead (attached to the pulse generator) is placed in a pocket created under the skin in the abdomen.
Although recovery with the epicardial approach is longer than that of the transvenous approach, minimally invasive techniques have enabled shorter hospital stays and quicker recovery times.
The doctor will determine which pacemaker implant method is best for you.
What Will I Feel?
You will feel an initial burning or pinching sensation when the doctor injects the local numbing medication. Soon the area will become numb. You may feel a pulling sensation as the doctor makes a pocket in the tissue under your skin for the pacemaker.
When the leads are being tested, you may feel your heart rate increase or your heart beat faster. Please tell your doctor what symptoms you are feeling. You should not feel pain. If you do, tell your nurse right away.
How Long Does The Procedure Last?
The pacemaker implant procedure may last around 2 hours.
Will I Have to Stay In The Hospital?
Yes. You will be admitted to the hospital and stay overnight after the procedure. Usually you will be able to go home the day after your pacemaker was implanted.
Risks
What Are the Possible Risks of the Procedure?
A pacemaker implant is generally a very safe procedure. However, as with any invasive procedure, there are risks.
Special precautions are taken to decrease your risks. Please discuss your specific concerns about the risks and benefits of the procedure with your doctor.
The Risks of Having a Pacemaker
All medical procedures and devices can create possible problems, and the risk of a problem with a pacemaker is low.
Before the Procedure
Taking Medication
If you take Coumadin, the results of your INR test (a blood test to evaluate the blood clotting) must be within a suitable range before the implant procedure can be performed. Usually you will be instructed to stop taking aspirin or Coumadin (warfarin) a few days before the procedure. Other blood thinners that will need to be held include dabigatran, rivaroxaban, apixaban, and edoxaban.
Your heart specialist may also ask you to stop taking other medications, such as those that control your heart rate. If you have diabetes, ask the nurse how to adjust your diabetes medications or insulin.
Do not discontinue any of your medications without first talking to your healthcare provider. Ask your doctor which medications you should stop taking and when to stop taking them.
How to Prepare
- Eat a normal meal the evening before your procedure
- Do not eat, drink, or chew anything after midnight before your procedure
- This includes gum, mints, water, etc.
- If you must take medication(s), take with small sips of water
- When brushing your teeth, do not swallow any water
- Remove all makeup and nail polish
What to Bring
- A family member to wait with you before the procedure
- Comfortable, easy-to-fold clothing
- Toiletries and any other items you would like to make your stay more comfortable. Please note, these will be kept with whomever accompanies you
- A one-day supply of your prescribed medications
- Do not bring any jewelry, watches, and/or valuables
After the Procedure
What to Expect After the Procedure
In your hospital room, a special monitor (telemetry monitor) will continually monitor your heart rhythm. The telemetry monitor consists of a small box connected by wires to your chest with sticky electrode patches. The box displays your heart rhythm on several monitors in the nursing unit. The nurses will be able to observe your heart rate and rhythm.
You will also have a monitor (small recorder) attached to your chest with sticky electrode patches. The holter monitor records your heart rhythm for 12 hours to ensure that the pacemaker is functioning properly.
A chest X-ray will be done after the device implant to check your lungs and the position of the device and leads. Before you are discharged, the monitor will be removed, and the results will be given to your doctor.
For your safety, a responsible adult must drive you home. Ask your doctor when you may resume driving.
Care for the Insertion Site
You may feel discomfort at the device implant site during the first 48 hours after the procedure. Call your doctor or nurse if your symptoms are prolonged or severe.
Keep the area where the device was implanted clean and dry. Do not scrub the area. Steri-strips may be covering the wound site; they may be removed 3 weeks after the date of the implant. Do not cover the wound unless you have been instructed to do so. You do not need to keep the wound covered with a bandage. Do not use creams, lotions, or ointments on the wound site.
Look at the area daily to make sure it is healing properly. Call your doctor if you notice:
- Increased drainage, bleeding, or oozing from the insertion site
- Increased opening of the incision where the device was implanted
- Redness, swelling, or warmth around the device insertion site
- Increased body temperature (greater than 101 degrees Fahrenheit)
You may take a shower 5 days after the procedure.
How the Leads Are Tested
After the leads are in place, they are tested to make sure they function properly and can increase your heart rate. This lead function test is called pacing. Small amounts of energy are delivered through the leads into the heart muscle. This energy causes the heart to contract.
Once the leads have been tested, the doctor will connect them to the pacemaker. The rate and settings of your pacemaker are determined by your doctor. After the pacemaker implant procedure, the doctor uses an external device to program final pacemaker settings.

Cell Phones
While your cell phone may not affect your pacemaker, to be safe, use your cell phone on the side opposite of where the device was implanted. Cell phones should not be placed directly against the chest or on the same side as your device.
Headphones
Certain types of headphones may contain a magnetic part that can affect pacemaker function. Keep headphones 1-2 inches away from your pacemaker. Do not keep your headphones in the breast pocket of a shirt or drape them around your neck.
Security Devices
If you must pass through entrances where anti-theft devices or metal detectors are being used for security, be sure to walk quickly through them. If handheld metal detector scanning is necessary, tell the security personnel that you have a pacemaker. You should not hold the metal detector near the device for any length of time.
Powerful Magnets, Magnetic Fields, and Equipment
You will need to avoid strong electric or magnetic fields, such as:
- Some industrial equipment
- Ham radios
- High-intensity radiowaves
- Arc resistance welders
Magnetic Resonance Imaging (MRI)
Some devices are compatible with MRIs. If you have been instructed to have an MRI, contact your implanting physician about the type of device that you have implanted and if this type of testing is safe for you.
Hybrid Cars
Stay about 2 feet away from the engine, and do not keep your smart key near your device. Do not put it in a pocket that is over your device.

Carry an ID Card
You will receive a temporary ID card that tells you what type of device and leads you have, the device manufacturer, the date of the device implant, and the name of the doctor who implanted the pacemaker.
Within three months, you will receive a permanent ID card from the device company. It is important to carry this card at all times in case you need medical attention or to tell people you have a pacemaker.
Let your healthcare providers know you have an implanted device. In rare occasions they may want to adjust your treatment plan because you have a pacemaker or defibrillator.
Airport Security
For patients who travel outside of Houston, our cardiology specialists recommend taking a few precautions. Should the security personnel use a wand to clear people, show them your card, and ask them to avoid placing the wand over your implanted heart device. Ask security if there is another method for clearance.
