相对不应期:在绝对不应期之后,细胞的兴奋性逐渐恢复,受刺激后可发生兴奋,但刺激必须大于原来的阈强度,这段时期称为相对不应期。
及心房相对不应期 RRPA
心房相对不应期 atrial relative refractory period ; ARR ; ARRP
室相对不应期 ventricular relative refractory period ; VRRP
房相对不应期 atrial relative refractory period ; ARR
心室相对不应期 ventricular relative refractory period ; VRRP
称为相对不应期 Relative refractory period ; RRP
相对不反应期 relative refractory period
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。
The relative refractory period, functional refractory period and effective refractory period (ERP) of right atrial, atrioventricular node and right ventricle were increased.
结果显示:特发性房颤患者的心房有效不应期缩短,相对不应期延长,早搏刺激的房间传导延缓显著增加。
The results showed that patients with IAF had shorter atrial effective refractory periods and longer atrial relative refractory periods, and also longer interatrial conduction delays.
