High-resolution activation mapping may provide more accurate isthmus sizing than entrainment mapping to better guide ablation therapy for postinfarction VT.
Abstract
In postinfarction reentrant VT, conduction velocities are slowest at the proximal and distal curvatures. Entrainment mapping overestimates the true size of the isthmus. High-resolution activation mapping of VT may better guide ablation therapy.
