Single-chamber pacemaker surgery takes about an hour, double-chamber pacemaker surgery a little longer. It is usually performed under local anesthesia. Implanting a pacemaker is painless. How exactly does the procedure of implanting a pacemaker work?

Pacemaker( Pacemaker ) heartregulates the heart and improves quality of life and lengthens them. Thanks to the development of medical technology, the operation of pacemaker implantation is now a relatively simple procedure, usually not requiring opening the chest. If the doctor offers such a procedure, do not be afraid of it. Pacemaker implantation can take place in the operating room or in the invasive cardiovascular laboratory.

Pacemaker implantation: the course of the procedure

The course of a pacemaker implantation procedure depends on its type. Single chamber pacemaker implantation is as follows:

  • under local anesthesia, the skin is incised in the subclavian area
  • the electrode is inserted into the heart through the guide wire
  • the tip of the electrode is attached in the area of ​​the right atrium
  • using an external test device, the conditions for stimulating the electrode with electrical impulses that are generated by a small stimulator powered by a battery are established
  • stitches are used to prevent the electrode from changing its position
  • the stimulator connects to the electrode
  • a special subcutaneous "pocket" is made
  • a small pacemaker with a battery is inserted into this subcutaneous pocket and sutured, placing it just under the skin at the level of the heart.

The implantation of a double-chamber pacemaker is similar, except that two electrodes must be inserted into the heart through the veins.

Where is the pacemaker implanted?

The location of the implanted pacemaker in the chest depends on the information collected in the medical history, comorbidities and the profession. the choice of site may be influenced by, for example, a history of collarbone fractures or the superior vena cava syndrome. When the doctor has no objections, the patient can choose the place to place the pacemaker.

Where is the implantation of the pacemaker?

Most often, a pacemaker is implanted through an incision in the skin below the collarbone, medially from the deltoid-thoracic furrow. Preferred routes of pacemaker implantation:

  • cephalic vein in the deltoid thoracic sulcus
  • subclavian vein

Alternative methods of pacemaker implantation:

  • external jugular vein or its branches: inferior disc vein or transverse vein of the neck
  • internal jugular vein
  • femoral vein in cases of superior vena cava syndrome.

Pacemaker implantation: preparing the patient for the procedure

First of all, the patient should be vaccinated against hepatitis B. Besides, he should:

  • fasting for at least 6 hours before treatment
  • may take medication on the day of the procedure, but only if you drink a small amount of fluids
  • in the case of anticoagulation treatment, it is necessary to modify it so that the INR level is below 1.75

Before the procedure, a sedative and local anesthetic are given. Only in some cases, general anesthesia (anesthesia) is used.
