Conclusion The extent of atrial fibro sis was increased in abdominal aorta banded rats. Although longer P wave duration and IACT are present, there is no change in atrial effective refractory period.
结论腹主动脉结扎大鼠心房纤维化程度增加，P波时限增宽，IACT延长，心房有效不应期没有改变。
The relative refractory period, functional refractory period and effective refractory period (ERP) of right atrial, atrioventricular node and right ventricle were increased.
心房、房室结及心室相对不应期、功能不应期及有效不应期(erp)延长。
