(57) [Summary] [PROBLEMS] A charge monitoring control information can be accurately extracted from a cardiac pacemaker implanted in a body without being disturbed by an AC electromagnetic field when charging a battery. Provided is a cardiac pacemaker device capable of suppressing an excessive charging applied voltage based on the same. When a living body implanting device receives a charge start command from outside the body, the living body charge information monitoring means and the like become active, and the extracorporeal percutaneous charging means changes the in-vivo battery. An intermittent generation of an AC electromagnetic field for charging the battery 53 causes the in-vivo control means 55 to transition to the charge mode operation, and receives a charge stop command from the transdermal charging means 1 outside the body, thereby causing the in-vivo The charge information monitoring means 105, 106 and the like are inactivated, and the control means 55 in the living body shifts to the non-charge mode operation. |
