Electromechanical Wave Imaging (EWI) Activation Maps

Caption

Electromechanical wave imaging (EWI) activation maps are capable of localizing the arrhythmic origin and differentiating irregular beats (right) from consecutive normal sinus rhythm beats (left) on the same patient before ablation. Red illustrates early and blue represents late activation (in milliseconds). The red arrow indicate the earliest activated region displayed by EWI, which successfully corresponds to the source of the arrhythmia in agreement with the site that was ablated with the intracardiac ablation site.LV = left ventricle, RV = left ventricle, ANT = anterior, POST = posterior.
