Cardiac implantable electronic devices are widely utilized to lower the rates of morbidity and mortality from ventricular tachycardia and ventricular fibrillation, as well as the incidence of sudden cardiac death. Although implantation of these devices increases survival rates, patients may experience acute and chronic complications. These complications include device dislocation and fracture, inappropriate shocks, pocket hematoma, or infection. Furthermore, functional loss in the upper extremity may result from upper extremity restrictions that are applied for an excessively long time in order to ensure proper placement of the device following implantation, or from patients who choose to extend this period on their own initiative out of worry about device failure or dislocation. Patients' quality of life may be negatively impacted by these issues as well as diminished exercise capacity, weariness, and weaker respiratory and peripheral muscles. A quality of life scale called 'The Assessment of Quality of Life and Related Events (AQUAREL)' was developed by Stoffmel et al. for patients using pacemakers. In this study, the validity and reliability study of the Turkish version of the AQAREL Scale will be conducted.

Inclusion Criteria:

• Having a pacemaker implant and not having any complications at the last pacemaker check-up,

  • Being in NYHA I-II-III-IV class,
  • Patients with no cooperation problems,
  • Volunteering to participate in the study.

Exclusion Criteria:

• • Patients with insufficient dementia or cognitive impairment due to multiple comorbidities (e.g., recent cerebrovascular accident and/or significant hypotension),

  • Patients with a history of psychiatric illness,
  • Patients with speech, hearing or intellectual disabilities.
