Localization of unstable intramural ventricular tachycardia circuit using live directional activation mapping
Intramural ventricular tachycardia (VT) is typically suggested by the results of suboptimal pace-mapping and conventional activation mapping from both myocardial surfaces. These findings are often insufficient to localize the intramural VT circuit. Additionally, hemodynamic instability further complicates accurate circuit localization. In this case study, we demonstrate a novel utilization of
