Caption: Virtual ECG. Computer simulation of a heart (pink) inside a torso (blue) with virtual ECG electrodes (yellow). Electrocardiography (ECG) records the heart's electrical activity with 12 electrodes (2 not seen). ECGs are used to diagnose and study heart disorders. This model was developed to study the electrical activity of the heart during the faulty heartbeats (arrhythmias) that may lead to a heart attack (cardiac arrest). The simulation requires massive computing power that takes 24 hours to generate one second of heart activity. Simulation results were presented in January 2002 by Dr Richard Clayton, leader of the team from Leeds University, UK, that developed the model.
