Figure 8From: Spatiotemporal representation of cardiac vectorcardiogram (VCG) signals Color coded dynamic VCG representation plot of a patient with dysrhythmia and atrial fibrillation. The irregular P wave morphology shows abnormal excitations from SA node to Atrial. The disappearance of red and appearance of green color in QRS loop also indicate abnormal locations of cardiac electrical axis (see animation video in Additional file 5).Back to article page
