This paper addresses EMC of an implantable artificial heart connected by a conducting wire (drive line) and influence of the emitted electromagnetic noise on the human body. Conducting wire length and human height may cause electrical resonance. At such times, the current through the conducting wire and the human body could increase conspicuously. We determined the current passing through the human body attached the conducting wire by both FDTD electromagnetic simulation and experimental observation. A cylinder model was used to imitate the human trunk. It was placed at the center of a shield room and subjected to electromagnetic plane waves with wavelengths ranginge from 80 MHz to 1 GHz. Experimental results show that the current through the human body was generally in the range of 0.25-2.3 mA (100-400MHz) with three remarkable current peaks. Simulation results show higher average current and lower peak frequency compared to the experimental results.
