No. The majority of cardiac arrest survivors do not receive an ICD (implantable cardioverter-defibrillator). Whether an ICD is appropriate depends on the underlying cause of the cardiac arrest, the condition of the heart, and a range of clinical factors assessed by a specialist cardiologist.
For some survivors, particularly those whose cardiac arrest was caused by a shockable heart rhythm with an identifiable and treatable underlying cause, other treatments may be sufficient. For others, particularly those at ongoing risk of a life-threatening arrhythmia, an ICD may be recommended.
The decision about whether to implant an ICD is made by your clinical team in consultation with you. If you have questions about your treatment, your cardiologist or cardiac nurse specialist is the right person to ask. You can also read more in our guide to implantable devices.
