Positioning and fixation of pacemaker leads in the right atrium depends on advanced anatomic knowledge in order to correctly interpret information from fluoroscopy and electrograms. Particularly the inability to reach a certain position or to achieve lead stability requires familiarity with right atrial structures such as the Eustachian ridge or areas of trabeculated versus smooth myocardium. Only a good understanding of right atrial anatomy makes it possible to replace electrophysiologically suboptimal atrial pacing sites such as right atrial appendage or high lateral wall by electrophysiologically better septal atrial pacing sites.
起搏器导线在右心房的定位和固定取决于先进的解剖学知识，以便正确解读透视和电图信息。特别是，如果无法达到特定位置或实现导线稳定，就需要熟悉右心房结构，如耳咽管嵴或小梁化与平滑心肌区域。只有对右心房解剖结构有很好的理解，才能用电生理学上更好的间隔部心房起搏部位替代电生理学上不理想的右心耳或高外侧壁起搏部位。
