Automatic identification of the arrhythmogenic substrate of scar-related ventricular tachycardia from electroanatomical electrical mapping data (Ref.TEC0136)

Voltage mapping is the technique used for assessing the arrhythmogenic substrate in scar-related ventricular tachycardia (VTs). The presence of slow conducting channels (CCs) within the scar (small bundles of viable myocardium) allows the induction and perpetuation of those VTs.

The automatic algorithm identify the presence or absence of the delayed component (slow CC activation) for voltage mapping. It provides automatic tags for identifying the slow CC entrances considered the target for ablation. It also associates the correct bipolar voltage to the electroanatomical voltage map in order to correct delineate the scar and identify the slow CC locations.

It is based on a complete solution that also is ready for performing activation mapping of more stable VTs like those with focal origin.
