Viewing Ventricular Fibrillation: Detailed 'Movies' of Deadly
Heart Irregularity May Lead to New Controls
In a report published
in the March 5 issue of the journal Nature, an international
team of medical researchers -- including a Georgia Tech physicist
-- moved one step closer to understanding the causes of ventricular
fibrillation through a remarkable series of high-resolution movies
that clearly show how the condition disrupts the electrical signals
that normally govern the heart. The unique high-speed imaging system
produced for the research also revealed for the first time that
ventricular fibrillation may develop in two distinct phases.
