92 Cardiac Defibrillation

Home monitoring of Pacemakers trans-telephonically was introduced in 1971 and remained until recently the main technology to remotely follow the performance of PMs. It was mostly aimed at ascertaining the integrity of the system especially with regard to battery perform‐ ance and longevity, appropriate capture, and sensing.

Modern Remote wireless communication from the Cardiac implantable electronic devices (CIED) to a home communicator allows the transmission of the information gathered by the device regarding programming, test and alerts, to the clinician. It became the new standard for remote follow-up. [1-3]

The current CIEDs being interrogated remotely include implantable cardioverter defibrillator (ICDs), pacemakers, implantable loop recorders and implantable haemodynamic monitors. [2]
