Abstract
Electroanatomic mapping (EAM) involves the rapid acquisition of multiple electrical and anatomical points in order to create a three-dimensional map encompassing this data. These systems use magnetic, impedance or a combination of the two for the non-fluoroscopic location of the catheters. Data can be displayed on a recreated anatomic structure. This data includes activation times, voltage recordings and entrainment mapping. One of the original mapping systems the Localisa (© Medtronic plc 2015) has been replaced by three systems which are used most commonly in clinical practice which include CARTO (© Biosense Webster, Inc), NavX Precision (St Jude Medical, St Paul, MN, USA) and Rhythmia (Boston Scientific Way Marlborough, MA, USA). Despite advances in the automation of these systems it is important to examine electrogram quality and annotation otherwise the map may not make any sense.
