Aug 18, 2016 · This chapter focuses on the two most commonly used EAM systems in practice today. To localize catheters within the heart, the first uses a magnetic field (magnetic electroanatomic mapping [MEAM]) and the second uses electrical impedance fields (electrical impedance electroanatomic mapping [EiEAM]).

Electroanatomic mapping (EAM) is one such advancement, allowing operators to record intracardiac electrical activation in relation to anatomic location in a cardiac chamber of interest, during arrhythmia mapping. Several EAM systems are …

Feb 1, 2025 · The process of creating a map containing electrical and anatomical properties of a cardiac chamber is termed electroanatomical mapping (EAM). Additional areas of interest, such as the location of the sinus node, atrioventricular (AV) node or regions of abnormal conduction, can be tagged onto the EAM.

Cardiac mapping refers to the process of integrating electrocardiographic information within a spatial–temporal framework, with the aims of defining the mechanism and propagation of arrhythmias, and identifying suitable targets for curative ablation.

Jun 26, 2021 · A fundamental principle of 3D EAM is the ability to collect anatomic (location) and electrical (electrograms) data simultaneously. This means that as the catheter connected to the 3D EAM system is moved in a cardiac chamber, serial recording of location data allows replication of the catheter tip’s location in real time on a computer monitor.

Oct 6, 2022 · Infiltrating adipose tissue (inFAT) has been recently found to co-localize with scar in infarcted hearts and may contribute to ventricular arrhythmias (VAs), a life-threatening heart rhythm...

To characterize cardiac activity and arrhythmias, electrophysiologists can record the electrical activity of the heart in relation to its anatomy through a process called cardiac mapping (electroanatomic mapping, EAM).

Contemporary three-dimensional (3D) EAM systems (EAMS) have significantly reduced the need for fluoroscopic visualisation of catheters. 2,3 They have also created a precise and trustworthy ‘virtual environment’ capable of guiding complex mapping and ablation procedures.

Electroanatomic mapping (EAM) systems have created a paradigm shift for the electrophysiologist by enabling 3D reconstruction of cardiac anatomy and nonfluoroscopic visualization of mapping and ablation catheters.

Feb 27, 2024 · EAM is now a central pillar in interventional therapy for a wide array of supraventricular and ventricular arrhythmias, and has been shown to improve safety, efficiency, and, in some arrhythmias, efficacy. Current EAM systems are comprehensive and accurate.
