UrduIn this week’s Chaos, researchers used an electrophysiological computer model of the heart’s electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They discovered far less energy is needed than is currently used in state-of-the-art defibrillation techniques. The authors applied an adjoint optimization method and discovered adjusting the duration and the smooth variation in time of the voltage supplied by defibrillation devices is a more efficient mechanism that reduces the energy needed to stop fibrillation by three orders of magnitude.

Researchers Map Rotating Spiral Waves in Live Human Hearts
Researchers at the Georgia Institute of Technology and clinicians at Emory University School of Medicine are bringing a new understanding to these complicated conditions with the first high-resolution visualizations of stable spiral waves in human ventricles.
Spiral Wave Teleportation Theory Offers New Path to Defibrillate Hearts, Terminate Arrhythmias
Researchers from the Georgia Institute of Technology offer a new method to disrupt spiral waves that uses less energy and that may be less painful than traditional defibrillation.
‘M-RISE’ Research Program Aims to Prevent Brain Damage Caused by Cardiac Arrest
ANN ARBOR, Mich. – For the more than 350,000 Americans that experience an out-of-hospital cardiac arrest each year, less than 1 in 10 of those treated will survive with good neurologic function. “Survival for these patients decreases with every minute there is a delay…
