Cardiac arrhythmia is a condition in which there is abnormal electrical activity in the heart.   During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. The   arrhythmia could be dangerous to human being depending on the beating speed and type of   abnormal rhythm. Some types of arrhythmia are serious or even life threatening, because on   those situations, the heart may not be able to pump enough blood to the body, then the   organs, especially the brain, will be damaged because of ischemia.

In order to assist medical students and instructors   in understanding and showing the underlying   electrophysiology and the effects of medical   treatment for various types of arrhythmia, we are   developing the visualized heart model based on   dynamic, three-dimensional virtual-reality, jointly with Peter Ott, MD of the Sarver Heart Center, the University of Arizona. Currently, this model could reflect the atrial flutter phenomenon and show the effects of tissue ablations on the electrical pathways in the heart. We are working on creating the heart beat animation linked with electrocardiogram synchronized, and presenting different types of supra ventricular tachycardia on it.
