Improving rates of implantable cardioverter defibrillator deactivation in end-of-life care.

Implantable cardioverter defibrillators (ICDs) save lives in selected patients at risk of sudden cardiac death. However, in patents suffering with terminal illness, ICD therapy could pose a risk of unnecessary futile shocks which could lead to undignified discomfort in their final days of life. National guidelines advise that patients approaching the end of their natural life should be offered a compassionate choice of having their defibrillator deactivated.
