This project aims to improve the effectiveness of ventricular tachycardia (VT) ablation procedures 
by accurately mapping the reentrant channels responsible for the arrhythmia. The study compares 
different mapping techniques, including bipolar, orthogonal, and omnipolar signals, using the HD 
Grid catheter and the EnSite X system. Electro-Anatomical Maps (EAMs) created through these 
techniques are evaluated for their accuracy in identifying channels by comparing them with Cardiac 
Magnetic Resonance (CMR) maps. The project's findings demonstrate that the omnipolar map, 
optimized with specific thresholds, exhibits higher correlation with the CMR map, offering reliable 
and accurate information about the cardiac tissue. Moreover, the comparisons are done also 
between layers of the ventricle’s heart, the layer 50 (which is an average of the pixels of layers 10-
50) is identified as the most informative layer, and expanded maximum thresholds allow for a 
comprehensive understanding of ventricular tissue. The results validate the superiority of the 
omnipolar technology and emphasize the need for further research and collaboration to advance 
the field of VT ablation procedures.
