Figure 8 This is a schematic illustration of the axis-illusion phenomenon.
A and B are frontal mean QRS axes of -90° and +90° respectively, suggesting a 180° divergence. Their sagittal projections reveal that this is illusory since they are actually much closer in space. Concept adapted from David Spodick’s work.
