[Effects of chronic intermittent hypoxia on atrial electrical remodeling in rats].

Objective: The aim of this study was to investigate the effects of chronic intermittent hypoxia (CIH) on atrial electrical remodeling in Sprague-Dawley (SD) rats, which provide the explication for the mechanisms of CIH promoting atrial fibrillation (AF).

Methods: Eighty SD rats were randomly divided into 2 groups: control group and CIH group (=40). CIH rats were subjected to CIH 8 h/d for 30 days.
