Iranian Patients' Experiences of the Internal Cardioverter Defibrillator Device Shocks: a Qualitative Study

Implantable Cardioverter Defibrillator (ICD) is a valuable treatment for the patients at risk of sudden cardiac death. In this method, after diagnosis of pathological cardiac rhythms, shock is automatically applied to normalize the rhythms. Shock is discharged when the patients are conscious, but the patients' experiences of shock have remained unknown. Thus, this study aimed to identify and describe the patients' experiences of shocks received from ICD.

The present qualitative study was conducted through thematic analysis and semi-structured interviews on 9 patients mean age 41.55 (1.57) with ICD from November 2013 to July 2014. Data analysis was also performed simultaneously using constant comparative analysis.

In this study, two main themes, namely "with a parachute for life" and "Faced with nuisance", were obtained representing the patients' experiences regarding ICD shock. With a parachute for life included subthemes, such as "Rebirth", "Comforter and healing", and "Life assurance". In addition, "Faced with nuisance" consisted of 2 subthemes of "Discomfort in moments of shock" and "Displeasure after shock".

This study provided a basis for evaluation of patients nursing after discharge. By identification of the patients' experiences regarding shock, the present study can help the professional health staff to efficiently play their roles and provide patients with holistic care. It can also be effective in designing behavioral and cognitive interventional programs to change the patients' attitude and promote their adaptation with their conditions.
