Pacemaker and defibrillator implantation

The pacemaker (cardiac stimulator) and the implantable automatic defibrillator are small electronic devices placed under the skin, usually below the collarbone, and connected to the heart by leads. The pacemaker stimulates the heart when it beats too slowly, while the defibrillator continuously monitors the heart rhythm and delivers automatic treatment in the event of a serious rhythm disorder. Implantation is a short, well-standardised procedure, most often performed under local anaesthesia supplemented by light sedation. The leads are introduced through a vein and positioned in the heart under X-ray guidance, then connected to the generator slipped under the skin. These modern devices are discreet, reliable and have a long battery life. They are checked regularly in consultation, making it possible to verify their operation and adjust their settings without further intervention. At Clinique Pasteur Tunis, pacemaker and defibrillator implantations are performed by a team specialised in cardiac electrophysiology, under rigorous aseptic conditions, with a personalised follow-up programme after implantation.
