Assessment of Atrial Electromechanical Coupling and Influential Factors in Nonrheumatic Paroxysmal Atrial Fibrillation

Abstract

The atrial electromechanical coupling was significantly longer and the dispersion of P-A at left lateral mitral annulus was greater in PAF patients. The prolongation of P-A may be related to left atrial enlargement, long episodes of PAF and aging and the dispersion of P-A at left lateral mitral annulus to LAD.
