Impact of Sudden Cardiac Arrest and Implantable Cardiac Defibrillator Shocks on Mental Health: Review and Management Guidance

Abstract

Survivors of sudden cardiac arrest (SCA) and those who experience shocks from an implantable cardiac defibrillator (ICD-S) are at risk of developing unrecognized and untreated mental health (MH) symptoms. MH sequelae can include anxiety, depression, or post-traumatic stress symptoms which hinder one's ability to return to usual life and activity, impeding follow-up, health care seeking, and adherence to care plans. Addressing MH as part of a whole person care in such scenarios could lead to improved wellness and recovery. This review examines the MH sequelae of SCA and ICD-S, explores potential therapies for managing these issues, proposes strategies to improve MH post-SCA or defibrillator shock, and identifies areas for future research.
