Treating or Killing? The Divergent Moral Implications of Cardiac Device Deactivation

Abstract

In this article, I argue that there is a moral difference between deactivating an implantable cardioverter defibrillator (ICD) and turning off a cardiac pacemaker (CP). It is, at least in most cases, morally permissible to deactivate an ICD. It is not, at least in most cases, morally permissible to turn off a pacemaker in a fully or significantly pacemaker-dependent patient. After describing the relevant medical technologies-pacemakers and ICDs-I continue with contrasting perspectives on the issue of deactivation from practitioners involved with these devices: physicians, nurses, and allied professionals. Next, I offer a few possible analyses of the situation, relying on recent work in medical ethics. Considerations of intention, responsibility, and replacement support my distinguishing between ICDs and CPs. I conclude by recommending a change in policy of one of the leading cardiac societies.
