Simulation of two-dimensional activation maps in the heart
Heart activation images were generated by computer simulations using an electrophysiological model that incorporates recent data on cardiac tissue properties and arrhythmia mechanisms. The model parameters were adjusted so that the heart's activity is synchronized with the EKG signals. Each simulation lasts between 10 and 25 seconds.
To our knowledge, the generated images are the most accurate commercially available 2D animations of the heart's electrical activity.

More than 30 arrhythmias and conduction abnormalities

Documentation
Each arrhythmia case is documented. The help includes different sections such as description of the arrhythmia, EKG characteristics, and electrophysiological mechanisms. Related arrhythmias that are not included in the software are also discussed.
Figures and diagrams are included to illustrate important concepts. A separate chapter introduces basic concepts of cardiac electrophysiology and mechanisms of arrhythmogenesis.

Limitations
- The heart is a complex three-dimensional structure. Our simulations, which are based on a two-dimensional model of the heart's electrical activity, portray a simplified projection of the three-dimensional activation maps observed in epicardial and endocardial measurements during electrophysiological experiments.
- The number of EKG leads is limited to two.
