The loop display shows the vector loops of T wave (repolarization) as well as of R wave (depolarization) running concurrently and nearly congruent. The main direction of each heart beat, (orange direction vector) is pointing toward apical. The end points of each direction vector are transferred into the globe view. The perspective here is directed towards the cardiac apex, which is located in the center of the display (apical sectors are shaded in grey). Basal areas are in white. The T maximum vectors are within the reference range (green) and are concentrated. The R maximum vectors are also within the reference range (blue) and also concentrated, which is typically a normal finding.
