Abstract :
The appropriateness of neglecting bulk myocardial anisotropy in forward ECG simulations was investigated via simulation. A current dipole was placed inside a cube that represented the myocardium. This cube was, in turn, placed inside a larger cube that represented the torso. The potential distribution due to the dipole was computed for different myocardial anisotropies using the finite element method. The simulation results show that bulk myocardial anisotropy can influence surface potential distributions under certain conditions
