MagnetoHemoDynamics simulations for ElectroCardioGrams

In presence of a high magnetic field, the blood flow in the aorta induces an electrical potential which is responsible for an increase of the $T$-wave in the electrocardiogram (ECG).
This phenomenon may perturb ECG-gated imaging. The aim of this study is to reproduce this
experimental observation through computer simulations. The proposed model consists of three components: magnetohydrodynamics (MHD) in the
aorta, bidomain equations in the heart and electrical diffusion in the rest of the body. These models are strongly coupled together and solved with finite elements. Some numerical results without and with a magnetic field are presented and discussed.
