An external device intended to enable a healthcare professional in a clinical setting to noninvasively extract data from an implanted cardiac pulse generator (i.e., therapeutic active cardiac implant) to obtain historic and/or current information on device performance, and may in addition be intended to communicate with a diagnostic cardiac implant (e.g., implantable cardiac monitor); it is not intended to program therapeutic implants and is dedicated to cardiac use. It includes a radio-frequency transmitter/receiver and may be intended to operate independently or in conjunction with a personal computer (PC)/tablet using dedicated software.
