Assessment of patients' perception of the use of an implantable cardiac electronic device.

The sample was a convenience sample from one university hospital outpatient clinic, so the results may not apply to other settings or populations. Most participants were professionally inactive, making it difficult to assess how pacemaker use affects work and why people retired. Patients were excluded if they answered three or more orientation questions incorrectly, so the findings may not represent people with impaired orientation. The study describes perceptions and does not test whether patient education, device use, or follow-up care changes outcomes.

Do not read the high satisfaction and security ratings as proof that pacemaker implantation works or that all patients adapt easily. This was a descriptive survey of 76 pacemaker users at one hospital clinic, and it reports patients’ perceptions, not treatment outcomes.
