Adivsor™ HD Grid Mapping Catheter, Sensor Enabled™ and EnSite™ Omnipolar Technology: Their Role in Complex Arrhythmia Mapping.

Multispline catheters were recently introduced and have led to significant improvements in electrogram acquisition and analysis. Omnipolar mapping is now able to be performed with these multispline catheters. Omnipolar mapping has the advantages of mapping a focal segment without needing the entire chamber of interest to be mapped, does not need a stable reference and is cycle length independent. This article will review the mechanism of omnipolar mapping and show how this technology can be used for multiple arrythmias. [ABSTRACT FROM AUTHOR]
