Results A total of 51 cases of patients with 6 cases of pacemaker dysfunction occurred: Pacing electrode catheter dislocation example 1 (1.9%), electrode fracture example 1 (1.9%), electrode insulation layer breakdown of example 1 (1.9%), 4 cases of perceptual dysfunction (7.8%), pacemaker-mediated tachycardia I example (1.9%), adopted to adjust the pacing parameters or replacement of pacemakers and pacing electrode catheter, pacing function returned to normal; 5-year follow-up, 3 cases of capsular hematoma and capsular rupture (5.9%), out by local hematocele, antibiotic rinse, closed cavity, in severe cases, re-incision and drainage to remove blood clots after compression bandaging article, in severe cases of infection, clear sinus, closed cavity, catheter inserted in the contra-lateral re-production of capsular bag implantation of pacemaker, to strengthen the anti-inflammatory treatment, made a very good effect. Two cases with pacemaker syndrome, 13 cases with cardiac dysfunction, 8 cases with cerebral infarction.

结果：51例患者中共有6例发生起搏器功能异常：起搏电极导管脱位、电极断裂、电极绝缘层破裂起搏器介导的心动过速各1例(1.9%)，感知功能障碍4例(7.8%)，通过程控或更换起搏器和起搏电极导管后，起搏功能恢复正常。5年随访中，囊袋血肿、囊袋破溃者3例(5.9%)，经局部抽出积血，抗生素冲洗，严重者重新手术后取得很好疗效；2例患者出现起搏器综合征，13例患者出现心功能不全，8例患者并发脑梗死。

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。

The results described above demonstrated that physiological AAI pacing increased CO remarkedly by preserving original LVEF and SV, while nonphysiological VVI pacing and physiological DDD pacing restricted the increase in CO as a result of reduced LVEF and SV.

其血流动力学效果表现为，生理性AAI起搏能在保持原有LVEF和较高SV较高的基础上，随起搏频率的增快，CO呈线性增加，而VVI和DDD起搏则由于LVEF、SV随频率增加而有所降低，致使CO增加受到限制。

The above results showed that physiological AAI pacing maintained a normal EAS and VAS, and improved or enhanced VSS; while nonphysiological VVI pacing and physiological DDD pacing induced the decrease in VSS due to an abnormal EAS and VAS. Furthermore, with increasing the pacing rate, VSS was markedly decreased.The quantitative comparison of parameters of left ventricular systolic function obtained by computerized ERNA showed that AAI pacing induced the significant increases in ventricular ejection rate and stroke volume with concomitant shortening of ejection time.

应用计算机-ERNA相位分析技术，对13例生理性AAI、13例非生理性VVI及6例生理性DDD患者，分别进行等相位电影，相位图，相位直方图和VSS参数的静动态观察和定量比较，结果显示：AAI起搏可维持正常EAS和VAS，心室相位均匀一致，并且VSS参数-相角程，半高宽和峰相位标准差均较起搏前分别降低，提示起搏后VSS有所改善或增强。

It showed that TPP is superior to bipole pacing in lowering pacing threshold, decreasing pulse breadth, keeping stable pacing and lessening of discomfort of the patients. Bipositive pole pacing is simpler in lowering pacing threshold and gives clearer pacing P wave and thus it is superior to hinegative pole pacing in TPP which is of practical value in TEAP.

但是，传统方法即二极起搏法的TEAP仍有许多不足之处，诸如：起搏阅值偏高，不适感觉常见而且明显，起搏效果欠稳定，脉冲波幅较大，伪迹明显等。

When the coronary sinus is unsuitable for transvenous biventricular pacing, a transseptal approach from the right to left atrium can allow endocardial left ventricular pacing with permanent anticoagulant therapy, instead of epicardial pacing via the branches of the coronary sinus.

当冠脉窦不适合经静脉双腔起搏后，右房至左房的隔膜通路手术需要经永久抗凝血疗法后进行左心室内膜起搏手术，而不是经冠脉窦分支的心外膜起搏。

Methods 102 patients with severe bradycardia were divided into two groups. 48 patients were given floating catheter transvenously for temporary cardiac pacing at bedside, while 54 patients were given regular transvenous cardiac pacing under X-ray direction. Operation achievement ratio, operation time, pacing parameter and complication incidence were observed in both groups.

102例严重心动过缓的患者，48例行床旁紧急置入漂浮电极导管进行心脏临时起搏，54例经X线透视下置入普通电极导管进行心脏临时起搏，对比观察两组手术成功率、手术耗时、起搏参数及并发症。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
