Abstract	The finite element method was applied in order to calculate current densities in the human torso induced by switched gradients of the magnetic field during MRI. The region of the heart muscle was in the focus of interest, because it is well-known that low-frequency currents could cause a stimulation process in human excitable tissues. Possible stimulation of the heart muscle or inducing the even more dangerous state of ventricular fibrillation can be fatal for the human being. Therefore the values of induced current densities were calculated in the heart muscle. An attempt was made to consider the influence of the current waveform. Finally, the obtained values were compared to the existing recommendations in the field.
