Chaos models might help predict cardiac arrhythmias.

Chaos models might help predict cardiac arrhythmias, say researchers Chaos models may someday help model cardiac arrhythmias – – abnormal electrical rhythms of the heart, say experts in the journal CHAOS, which is published by the American Institute of Physics lisää . Recently, medical study has drawn more focus on chaos in cardiac dynamics. Although chaos marks the disorder of a dynamical system, locating the origin of chaos and viewing it develop might allow researchers to predict, and maybe even counteract, certain outcomes. An important example may be the chaotic behavior of ventricular fibrillation, a abnormal center rhythm that is often life-threatening severely. One study discovered chaos in two and three measurements in the breakup of scroll and spiral waves, regarded as precursors of cardiac fibrillation.

Change in sickle cell anemia prevention strategies decreases racial disparities in stroke-related deaths The disparity in stroke-related deaths among black and white children dramatically narrowed after prevention strategies changed to include ultrasound screening and chronic blood transfusions for children with sickle cell anemia, according to research presented at the American Stroke Association’s International Stroke Conference 2012. Before stroke prevention efforts changed in 1998, black children were 74 % much more likely to die from ischemic strokes than white children.
