Simulated heart attack. Image 1 of 2. Computer simulation of the electrical activity of the heart during a heart attack. This image shows the start of a pulse of electrical activity (red area at upper left). This will spread in a wave over the unactivated heart surface (blue) towards lower right. The wave should be smooth and cause the contraction of the heart muscle to send blood around the body. Disruption to this process during a heart attack (myocardial infarction) may cause ventricular fibrillation, shown in image M172/448. Simulation results were presented in January 2002 by Dr Richard Clayton, leader of the team from Leeds University, UK, that developed the model.
