An implanted pacemaker can only communicate with the outside world through its window, i.e., the clinical programmer. Since its inception, the pacemaker has evolved from a non-programmable device to a complex device. Therefore, programming a modern implantable pacemaker could be very challenging for non-experienced or infrequent users. Various programmer-based automatic functions have been developed to reduce programming time and complexity and to obtain accurate measurements. With increasing interests in the telecommunications and information exchange, these programmer-based automatic functions are pushing forward a future vision that automatic pacemaker follow-up procedures via telecommunications are possible for patients located in any corner of the globe.
