Abstract
Abstract An electrocardiograph system which enables safe data transfer with high reliability between a portable electrocardiograph and a recorder, such as a printer, and in which an effect of leakage magnetism is taken into consideration. In the electrocardiograph system, electrical signals and/or electric power are transferred between the electrocardiograph and the recorder by electro-magnetic coupling therebetween using independent coils. The electrocardiograph system is further provided with a device for rejecting noise of an electric power signal from the electrical signals or noise of an electrical power signal and a clock signal from a data signal.
