Table 3 Results for automatically calculated peak velocities and atrial contraction. Manual and automatic measurement results of automatically calculated peak emptying velocity, peak filling velocity, and atrial contraction as mean ± SD in the left and right side of the heart. Comparison of automatic tracking vs manual measurements as correlation R value and bias ± SD. The validation was performed on n = 20 subjects. The atrial contraction is given in % of the atrioventricular plane displacement (AVPD) in end systole
