Visual interpretation of the state diagram. One heart beat corresponds to all 360° in the state diagram, starting with Pre-Ejection and ending with Atrial Contraction. The state diagram contains regional information from seven positions in the heart and global information represented by the mean time intervals. The outermost circular segment in the state diagram corresponds to the antero-septal wall, followed by the anterior, antero-lateral, infero-lateral, inferior, infero-septum (LV) and medial wall (RV). The global function of the left ventricle was an average of six measuring points, while the only measuring point in the right ventricle represented regional function.
