A real time ECG simulation tool for education and research that enables users 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. By altering tissue level characteristics of the heart, users can immediately observe the changes in the resulting ECGs and BSPMs.

ECGSim was created and is maintained by PEACS BV, a company specialized in creating computer software for academic medical research and education.

A Problem Solving Environment (PSE), for modeling, simulation, and visualization of scientific problems. SCIRun now includes the biomedical components formally released as BioPSE, as well as BioMesh3D.
