The Lived Experience of Sudden Cardiac Arrest Survivors: A Descriptive Phenomenological Study

Sudden cardiac arrest (SCA) is a life-threatening event that profoundly affects the physical, psychological, social, and overall well-being of survivors. Implementation of an implantable cardioverter defibrillator (ICD) may further contribute to psychosocial challenges, despite providing a sense of reassurance. However, the multidimensional and overall effects on SCA survivors with ICDs are not been fully understood.

In this study, our aim was to explore the lived experiences of SCA survivors with ICDs, focusing on adaptation, meaning in life, and insights to support psychological well-being and quality of life.

A descriptive phenomenological study was conducted using Giorgi's method. Semistructured interviews were conducted with 12 SCA survivors with ICDs at a tertiary hospital in South Korea. Data were analyzed using Giorgi's phenomenological method to identify essential themes of the participants.

Five major themes and the subthemes emerged: (1) Resuscitation on the Threshold of Death, (2) Instability within Stability, (3) A Life Disrupted from the Ordinary, (4) Enduring Daily Life Alone and Moving Forward, and (5) Embracing an Imperfect Second Life. Each theme comprises 2 to 4 subthemes. In Theme 3, 2 unique subthemes emerged: anxiety about harming others and hesitancy toward marriage.

The findings highlight the psychosocial challenges of SCA survivors with ICDs, emphasizing common experiences and unique concerns. These results underscore the need for long-term psychological support, social reintegration, and tailored interventions to enhance quality of life. By addressing both shared and distinctive experiences, the study deepens understanding of survivors' adaptation and provides a foundation for patient-centered care programs.
