[Deactivation of implantable cardioverter defibrillators (ICD) at the end of life].

Up to one third of patients with an implantable cardioverter defibrillator (ICD) experience shock discharges in the last 24 h before death, which no longer have any therapeutic benefit. Even in patients who have a living will (do not resuscitate, DNR, directive), the shock function of the ICD is activated in over 50% of those affected 24 h before death. A significant subgroup of ICD wearers must therefore experience painful, significantly stressful and unnecessary ICD shocks at the hour of their death. All available position papers on this topic call for patients to be informed about this issue in good time; however, in reality such a conversation almost never takes place. This paper outlines the legal basis that helps doctors to deactivate the ICD in the final stage of life and the specific conditions that must be met. This paper advocates repeatedly addressing the issue during the course of the illness and to involve relatives. The actual conversation about deactivation at the end of life should be proactively initiated by the responsible attending physician and should take the form of a structured, patient-centered dialogue in the spirit of good dialogue.
