A professor of medicine at Stanford University, Dr. Sanjiv M. Narayan has dedicated much of his professional life to addressing unmet medical needs in the area of atrial fibrillation. Recent research into the dipole density mapping of atrial fibrillation has reproduced key findings made by Dr. Sanjiv Narayan in the early 2010s.
Whether derived from contact or non-contact sensors, traditional voltage-based electrocardiograms show electric field measurements that include surrounding activation sources as well as the targeted activation source. When mapping heart activity, this can result in a blended map that may fail to display particularly detailed rhythmic patterns. Dipole density mapping, by contrast, has an increased ability to produce a sharp and clearly delineated cardiac activity display because it solely represents localized charge-sources on the heart’s interior chamber surface.
The dipole density mapping process involves the insertion of a cardiac catheter with
non-contact sensors to measure dipole density within the heart. These sensors feed information to computer software that can produce a continuous view of each heartbeat and arrhythmia.
