In the coupled-cell model, Ist significantly enlarged the gap conductance region where stable BP cell pacemaking and NP cell driving occur, reducing the number of BP cells required for robust pacemaking and driving.

在配对细胞模型，Ist明显扩大出现稳定BP细胞起搏和NP细胞驱动的缝隙电导区域，这就降低了稳定起搏和驱动所需要的BP细胞的数量。

Objective To make the patients who have received pacemakers implantation know which kinds of devices should be away from as impossible,and what steps should be take if the contiguity is unavoidable.Methods 17 in hospital patients who have received pacemakers implantation received our lecture,and explanation and words are used to make them know the correlated knowledge.Question and quiz are used to evaluate the degree of their prehension.

目的 使植入起搏器后的患者掌握应避免接触的设备，掌握接触后应采取的应对措施方法对住院17例行起搏器植入术的患者采取讲解与文字相结合的方法，对其进行相关知识宣教，通过提问及考试了解其掌握情况。

Regular followup and pacemaker parameter program have positive influence on psychological conditions of patients with a cardiac pacemaker by improving depression, anxiety and other symptoms.

术后增加定期随访和起搏器参数程控次数对心脏起搏患者心理状态有积极影响，可以改善患者术后焦虑、抑郁等不良心理症状。

Objective To evaluate the effects of pacing in right ventricular septum and right ventricular apex on biventricular synchrony.

目的 评价右心室间隔部起搏和右心室心尖部起搏对双心室同步性的影响。

By superfusion of ET-1, the hypoxiainduced decrease in RPF was remarkably potentiated (from 136±9 to 48±27 bpm) and the occurrence of pacemaker arrest was shifted to 20±6 min.

在缺氧的条件下持续灌流ET-1（1 nmol／L）20 min时，可显著加重缺氧所致的RPF降低，使起搏细胞的RPF由对照的136±9 bpm降至48±27 bpm（p.01），起搏细胞的停跳时间前移至20±6 min。

By superfusion of ET-1,the hypoxia-induced decrease in RPF was remarkably potentiated and the occurrence of pacemaker arrest was shifted to an earlier time. The h3,poxia-induced effects could be effectively attenuated after pretreatment with BQ-123,implying the role of endogenous ET-1 release in hypoxia-induced effects.

ET-1可显著加重缺氧所致的RPF降低，使起搏细胞停跳时间前移；而以ET*受体阻断剂BQ-123预处理窦房结标本后，则能有效地缓解缺氧对起搏细胞的效应，提示内源性ET-1的释放在缺氧效应中的作用。

Objective To explore the clinical feasibility of right ventricular inflow tract posterior septal endocardium pacing ,in order to find another pacing site for tined electrode.

目的 探讨右室流入道靠后间隔心内膜起搏的临床可行性，为翼状电极寻找另一理想起搏部位。

Physiological pacing could improve cardiac function and living quality and decrease the occurrence of para atrial fibrillation and pacing syndrome, which is superior to unphysiological pacing. We should advocate physiological pacing.

植入生理性心脏起搏器能改善患者心功能，提高生活质量，起搏器综合征发生率低，值得推荐。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
