Abstract
Abstract System for detecting information in an artificial cardiac pacemaker by using energy supplied from the outside of the pacemaker. An energy supplying device supplies energy to the pacemaker from the outside. An energy receiving device in the pacemaker receives the energy. An energy changing device changes the received energy into information energy, according to the information from an information generating device. An information transmitting device transmits the information energy to the outside of the pacemaker.
