A leading researcher in atrial fibrillation (AF), Dr. Sanjiv M. Narayan operates as a professor of medicine and bioengineering at Stanford University, as well as director of the school’s electrophysiology research and atrial fibrillation programs. In 2017, a research group from Cambridge University published the study “Dipole Density Mapping of Atrial Fibrillation,” which reproduced many of the same results Dr. Sanjiv Narayan and his team had discovered in the 2012 paper, “Treatment of Atrial Fibrillation By the Ablation of Localized Sources.”
First published in the medical text European Heart Journal, the team responsible for the 2017 paper was led by Professor Andrew Grace, PhD, of Cambridge University. The researchers contend that a process known as dipole density mapping provides scientists with a more accurate representation of complex arrhythmias than the standard electrocardiogram. This is because the electrocardiogram is a voltage-based mapping system that can obscure complex patterns in arrhythmia by blending activities the dipole density mapping method is capable of delineating. Dipole density mapping delineates by measuring local charge-sources within the interior surface of the heart chamber being tested.
