Figure 5 Alignment of Registered Endocardial Voltage Map and 3-Dimensional Scar Map
Apical view displays endocardial voltage map using the conventional voltage criteria for endocardial scar of <0.5 mV displayed in red as seen in the color-coded scale displayed on the right. Superimposed 3-dimensional positron emission tomographic scar map demonstrates a large apical wall defect (hole) in the purple superimposed mesh signifying myocardial scar. Voltage-defined myocardial scar and adjacent area of abnormal myocardial voltage (green and yellow) align well with the area of positron emission tomographic-defined scar after registration. LV = left ventricle.
