We can use this applications for Cardiac Research, I also added some information about how this can be done.
The Xbox 360 system has a single chip (with 165 million transistors) for its CPU. This chip is in fact a three-way symmetric multiprocessor design.
With the help of this chip, one can model how electrical excitations in the heart move around damaged cardiac cells. This could be useful to investigate or even predict cardiac arrhythmias (abnormal electrical activity in the heart which can lead to a heart attack).
