Welcome to the Arrhythmias Gallery. This gallery contains three different exhibits: atria, ventricles, and spiral waves. The atria section features a rotating three-dimenisonal atrial structure developed at Duke University and animated "paintings" of different atrial arrhythmias involving spiral waves. The ventricles section includes a rotating three-dimensional ventricular structure developed at the University of California at San diego along with animated "paintings" of ventricular arrhythmias. The spiral waves mural depicts six different kinds of spiral wave trajectories.
