Finite element method for forward ECG calculation

Surgical interventions for treatment of cardiovascular diseases require accurate planning, which takes into account information about patients anatomy and heart activity. The activity of the heart is commonly monitored using a non-invasive electrocardiography (ECG) method. The results of personalized numerical modeling of ECG can be used to make the treatment planning more effective. In this paper we present a method for forward ECG modeling with the use of personalized torso model. We use texture-based analysis of patients computed tomography (CT) scans for obtaining the anatomical models of abdominal organs and investigate the influence of each organ on the simulation results. We present and analyze the detailed mathematical problem and its weak formulation. Also we propose a method for acceleration of ECG numerical modeling.
