Optimal Cardiac Rhythm during Substrate Mapping in Scar-Related Ventricular Tachycardia: Significance of Wavefront Direction on Identifying Critical Sites

A rotational activation pattern (RAP) around the localized line of a conduction block often correlates with sites specific to the critical zones of ventricular tachycardia (VT). The wavefront direction during substrate mapping affects the manifestation of the RAP and line of block.
