Stanford University professor Dr. Sanjiv M. Narayan is an expert in atrial fibrillation (AF), a medical condition defined by an irregular and often accelerated heartbeat. One of Dr. Sanjiv Narayan’s recent studies on the topic appeared in the June 2017 issue of the Journal of Cardiovascular Electrophysiology.
Entitled “Two Independent Mapping Techniques Identify Rotational Activity Patterns at Sites of Local Termination during Persistent Atrial Fibrillation,” the study addressed uncertainties in the general medical understanding of AF that arise as the result of inconsistent mapping techniques. It accomplished this by comparing two independent AF mapping techniques that measured results in the same patients.
The first study of its kind to use more than one AF mapping method, it identified stable rotational activation at specific sites in the heart that drove AF for multiple cycles. Both mapping methods confirmed these results. Researchers developed a new computer program to chart their findings and subsequently released this program for free on the Internet.
