Temperature distribution of whole body with a cardiac pacemaker by the low frequency band of the gradient magnetic field generated by the Helmholtz coils were simulated by low frequency solver and thermal simulator with steady state solver. Simulations were performed by 40mT/s of slew late and from 100Hz to 2500Hz of frequency of gradient magnet fields. Temperature near the center of the element of Helmholtz coil were higher and maximum temperature was 6.83e-03℃ at 1000Hz. The temperature around a cardiac pacemaker was less than 1.74e-04℃ at 1000Hz. The results leaded there was little substantial risk for heating in this case.
