Don't forget to hit load after you have selected one of the layouts.

This is a little applet designed to demonstrate the heart's electrical conduction system.  You can play around and create your own conduction system.  Note that the green squares are fast-conducting and the blue squares are slow-conducting.  The blue squares also have a longer refractory period. 

I have included a handful of systems I made.  You can select the one you want to see in the box at the bottom and click "Load".  They look a lot like the old Atari 2600 video games.  When Fire is selected, clicking the mouse over a square will cause it to act like a pacemaker. 

You can try a larger version here.
