双心耳的

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.

将6对双极记录电极分别缝于高位左、右和低位左、右心房外膜以及左、右心耳，采用心脏程序期前刺激法(S1S2)，分别测量基础起搏周长为300、250和200ms时的心房有效不应期、AERP频率适应性、AERP离散度、房颤诱发率及平均持续时间等电生理指标。

Method］ Puncture into Attain long sheath of CS through left infraclavicular vein,guided by CS pipe,take sheath into CS,make reverse contrast of heart vein with Attain saccule contrast pipe,put the left ventricle electric pole into the vein through sheath,then bring it into right ventricle apex and right cardiac ear through the electric pole of right ventricle and atrium,connect it with 3-cavity pulse generator,which is buried under left chest skin.

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。
