Fig. 8

Top: set of steps that can be used to estimate functional block line locations during premature stimulation and during reentrant ventricular tachycardia. ΔT is taken as the largest value of ΔT in the vector field about the measurement point. Lower: Maps of ΔT/T, maximum ΔT/T (shown as red – during premature stimulation and blue – during ventricular tachycardia), block line locations during premature stimulation (PS) and during ventricular tachycardia (VT). For simplicity, an area of large ΔT/T is shown at only one of the two isthmus ends. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
