摘要: Background The aim of this study was to examine whether left atrial (LA) strain and synchrony can be assessed using three-dimensional (3D) speckle-tracking echocardiography (STE) how 3D STE parameters are modified by fibrillation (AF). Methods LA peak ventricular systolic longitudinal (LSs), circumferential (CSs), area (ASs) pre–atrial contraction strain, (CSa), were determined STE, SDs times peaks regional calculated as indices dyssynchrony. Three-dimensional able measure in 75 the 77 healthy subjects all 47 patients with AF (31 paroxysmal [PAF] 16 permanent AF). Results mean time for analysis 18% shorter than two-dimensional (2D) ( P = .044), LSs .040), ASs .007), CSa .020) independent predictors PAF. Conclusions enables measurement both excellent reproducibility. appears beneficial compared 2D identifying
