Electroanatomic mapping of atrial tachycardia—Manual vs automated annotation

Electroanatomic mapping of atrial tachycardia—Manual vs automated annotation☆

Introduction The availability of novel mapping systems and software in combination with or without dedicated multipolar diagnostic catheters allows for automatic high-density 3-dimensional electroanatomic mapping that enables detailed insight into atrial tachycardia mechanisms. For the accuracy of the activation map, the consistency of electrogram annotation is crucial. Depending on the system ...

Electroanatomic mapping of the intercaval bundle in atrial fibrillation.

Principles of Electroanatomic Mapping

Electrophysiologic testing and radiofrequency ablation have evolved as curative measures for a variety of rhythm disturbances. As experience in this field has grown, ablation is progressively being used to address more complex rhythm disturbances. Paralleling this trend are technological advancements to facilitate these efforts, including electroanatomic mapping (EAM). At present, several diffe...

Application of ripple mapping with an electroanatomic mapping system for diagnosis of atrial tachycardias.

BACKGROUND Three-dimensional (3D) mapping is often used to guide ablation in atrial tachycardia (AT), but maps can be susceptible to annotation and interpolation errors. Ripple Mapping (RM) is a technique that displays electrogram time-voltage data simultaneously as dynamic bars on the surface shell to overcome these limitations. OBJECTIVES We hypothesized that RM would be superior to establi...

Electroanatomic mapping of arrhythmogenic right ventricular dysplasia.

OBJECTIVES We tested the hypothesis that spatial association of low-amplitude intracardiac electrograms can identify the presence, location and extent of dysplastic regions in arrhythmogenic right ventricular dysplasia (ARVD). BACKGROUND Arrhythmogenic right ventricular dysplasia is a right ventricular (RV) cardiomyopathy characterized pathologically by fibrofatty infiltration and clinically ...
