Figure 6 Study Results in a Representative Animal With Inducible VT

Positron emission tomography polarmaps (left) show regional distribution of [¹³N]-ammonia and [¹¹C]-epinephrine retention (top), along with perfusion (white) and innervation defects (blue; bottom). Segmental analysis (bottom right) shows that innervation defect exceeds perfusion defect predominantly in the distal anterior wall segment, highlighted in yellow. Three-dimensional electroanatomical maps, depicted in anterior view on top right, show reduced bipolar endocardial voltage in apex and distal septum/anterior wall. Propagation maps show earliest activation of VT in the infarct borderzone in the distal anterior wall (red arrow). Abbreviations as in Figures 1, 2, and 4.
