Left atrial mechanical dispersion

1. Left atrial mechanical dispersion is associated with atrial fibrillation in humans (HR 1.23 per 1 SD increment, 95% CI 1.03-1.48).

   “LA MD (HR per 1SD increment 1.23, 95% CI 1.03-1.48) were independently associated with incident AF after multivariable adjustment.”
