As a physician and software engineer, Sanjiv
Narayan, MD, PhD, was intrigued by an important question — Was
it possible to map the chaos of atrial fibrillation?
Starting in 2001, Narayan began using engineering and software
modeling to explore ways to track the sources of atrial fibrillation.
His analyses and patient studies revealed patterns pointing to
small, localized areas driving the disruptive electrical activity
behind Afib. Dr. Narayan’s research confirmed that these spots, called
rotors, were the origins of the chaotic electrical activity causing
Afib. Though experimental studies had shown evidence of such sites,
his work was the first to confirm their existence in patients with the
Drawing on his expertise in computers and neurophysiology, Dr.
Narayan collaborated with colleagues to develop the FIRM mapping
software and the elegant electric signal analysis used for FIRM ablation.
