The invention consists of a system for remote programming of an implantable medical device such as a heart pacemaker, defibrillator or the like, wherein the system includes a programmable personal device (e.g., an implant) and a service center. The service center has a programming monitoring unit which determines a programming time endpoint which depends on the point in time at which a programming order was sent to the implant, and which cancels or deletes the programming order if the service center has not received a programming confirmation confirming successful receipt, execution, and/or forwarding of the programming order by the implant by the programming time endpoint.
