Using DTI, the time intervals from the beginning of P\u2010wave to the onset of atrioventricular ring motion related to atrial contraction were measured.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Atrial electromechanical coupling at the interventricular septum atrioventricular annulus (P\u2010A1), left lateral mitral annulus (P\u2010A2) and right lateral tricuspid annulus (P\u2010A3) in PAF group were significantly longer than those in control (p &lt; 0.001). The difference between P\u2010A2 and P\u2010A1 (T1), P\u2010A2 and P\u2010A3 (T3) in PAF group were greater than those in control before age correction (p &lt; 0.05). The linear regression analysis showed that the duration of PAF episodes and age were the greatest influential factors of P\u2010A1 (r = 0.564). Left atrial anterior\u2010posterior dimension (LAD) and age were the greatest influential factors of P\u2010A2 (r = 0.459). The LAD was the greatest influential factors of T1 and T3 (r = 0.408, 0.542).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The atrial electromechanical coupling was significantly longer and the dispersion of P\u2010A at left lateral mitral annulus was greater in PAF patients. The prolongation of P\u2010A may be related to left atrial enlargement, long episodes of PAF and aging and the dispersion of P\u2010A at left lateral mitral annulus to LAD.
