New Targeting Technology Improves Outcomes for Patients With Atrial Fibrillation, University of California, Los Angeles (UCLA), University of California, San Diego (UCSD), Indiana University Study

In a landmark study of atrial fibrillation, researchers from UCLA, UC San Diego and Indiana University report having found for the first time that these irregular heart rhythms are caused by small electrical sources within the heart, in the form of electrical spinning tops ("rotors") or focal beats. Importantly, they found a way of detecting these key electrical sources and of shutting them down in minutes using a precisely targeted therapy with long-lasting results.
