What Happens During the Pacemaker Procedure?

The endocardial pacemaker implant takes about one to five hours to perform.

  • You will lie on a bed and the nurse will start an intravenous line (IV) into your arm or hand. This is so you may receive medications and fluids during the procedure. You will be given a medication through your IV to relax you and make you drowsy, but it will not put you to sleep.
  • The nurse will connect you to several monitors. The monitors allow the doctor and nurse to check your heart rhythm, blood pressure, and other measurements during the pacemaker implant.
  • Your left or right side of your chest will be shaved and cleansed with a special soap. Sterile drapes are used to cover you from your neck to your feet. A strap will be placed across your waist and arms to prevent your hands from coming in contact with the sterile field.
  • The doctor will numb your skin by injecting a local numbing medication. You will feel a pinching or burning feeling at first. Then, it will become numb. Once this occurs, an incision will be made to insert the pacemaker and leads. You may feel a pulling as the doctor makes a pocket in the tissue under your skin for the pacemaker. You should not feel pain. If you do, tell your nurse.
  • After the pocket is made, the doctor will insert the leads into a vein and guide them into position using the X-ray machine.
  • After the leads are in place, their function is tested to make sure they can increase your heart rate. This is called "pacing" and involves delivering small amounts of energy through the leads into the heart muscle. This causes the heart to contract. When your heart rate increases, you may feel your heart is racing or beating faster. It is very important to tell your doctor or nurse any symptoms you feel. Any pain should be reported immediately.
  • After the leads are tested the doctor will connect them to your pacemaker. Your doctor will determine the rate of your pacemaker and other settings. The final pacemaker settings are done after the implant using a special device called a programmer.
