Modeling the complex electrical waves that cause heart arrhythmias could provide the key to understanding and treating a major cause of death in the world. Until now, however, real-time modeling of those deadly waveforms within millions of interacting heart cells required especially powerful computer clusters – even supercomputers. Using graphics processing chips designed for gaming applications and software that runs on ordinary web browsers, researchers have moved this modeling of the deadly spiral wave heart arrhythmias to less costly computers – even high-end smartphones. That could put the real-time 3D modeling into the hands of clinicians who may one day use the system to diagnose and treat these abnormal heart rhythms.
