ECGSIM is an interactive simulation program that enables one to study the relationship between the electric activity of the heart and the resulting potentials on the thorax: PQRST wave forms as well as body surface potential maps.

It is intended to serve as both an educational and a research tool. In education its main application is to help students understand the relation between the activity of the heart and the ECG. The typical use in research is testing any hypothesis one may have regarding the manifestation of cardiac malfunctioning in the electrocardiographic wave forms on the thorax.
