Human Heart Simulation Software for Parallel Computing Systems

This study demonstrates a software system for simulating the electrical and mechanical activity of the heart left ventricle (LV). The distinguishing feature of the system is the use of the heart anatomy model, which is based on an analytic description of the ventricular shape and fibre orientation. Another important system feature is that the simulation takes into account relationships between the mechanical and electrical activities that occur in the LV (cardiac mechano-electrical coupling). We describe our model integration design, the software system architecture, and the parallel implementation of the system using OpenMP technology. We evaluate the performance and scalability of the software system. In addition, we provide two examples of simulation results.
