Dr. Sanjiv M. Narayan is a cardiac research scientist and a professor of medicine at Stanford University, where he founded the Stanford Arrhythmia Center. In his research for new treatment methods, Dr. Sanjiv Narayan participates in leading research projects.

Atrial fibrillation (AF) and atrial tachycardia (AT) often convert to and from one another, but little research has been performed on whether the two conditions are related on a mechanistic basis. Dr. Narayan and other researchers recently conducted a trial in which they hypothesized that critical areas related to AT may have a correlation to regional sources of AF in patients who experience both conditions.

The researchers tested their hypothesis with spatial mapping techniques on 26 different patients who experience AF to AT conversion. The researchers concluded that overlap may exist in atrial regions related to the mechanisms that cause both AF and AT. The researchers suggest that future studies should examine the rate at which accelerated AT causes AF.
