Figure 6. Impact of fully preexcited QRS morphology in lead aVF on the distribution of accessory pathways (APs) in patients with transition from negative QRS to positive QRS at V3. The right panel illustrates how, first with the disappearance of notch/slur the localization of APs shifts from the free wall to the septum, and then, with increasing negativity in lead aVF the point of maximum density shifts progressively more inferiorly on the septum (maps from the top to the bottom in the right panel).
