CardiacSimu : A Feasible Tool for Electrophysiological Study

Version 0.0.3.1

What is CardiacSimu

Electrophysiological studying (EPS) or the epicardial mapping are common methods in arrhythmia study. But the resolution is usually not enough for observing sophisticated arrhythmia phenomenon, and system dynamic responding time could not be neglected. Epicardial mapping needs a chest opening operation to implant many electrodes on the cardiac surface, which will disturb the cardiac state. So the cardiac model which can simulate cardiac activities is widely used as an auxiliary in the study.

CardiacSimu is a 3D cardiac model writen in C++ with high portability. It provides a platform for electrophysiological study. It can simulate action potential (AP) as well as propagation of the excitation according to AP waveform. It can also generate the isochronal map and isopotential map. Most exciting features of this tool set is total configuration of the simulation and anatomic structure. CardiacSimu can import any part of heart into simulation and make it discrete into units named simulating cell.The profile of single cell is configurable.
