Name a potential adverse event related to pacemaker implantation.

Infection at the implant site is recognized as a potential adverse event related to pacemaker implantation due to various factors associated with the surgical procedure. During implantation, the skin is incised, and the pacemaker leads are inserted into the heart through blood vessels, creating opportunities for pathogens to enter the body.

Infection can occur not only at the site of the incision but also within the pocket where the pacemaker is placed. If appropriate aseptic techniques are not followed or if the patient has underlying conditions that compromise their immune system, this risk increases. Early recognition and treatment of infection are vital, as severe infections can lead to more serious complications, including the need for explantation of the pacemaker.

In contrast, while arrhythmias, thrombosis, and heart failure can also be concerns associated with heart disease and its management, they are not directly linked to the implantation process itself, making them less specific choices in this context.
