Pacing from the right ventricular apex is associated with long-term adverse effects on left ventricular function. This has fuelled interest in alternative pacing sites, especially the septal aspect of the right ventricular outflow tract (RVOT). However, it is a common perception that septal RVOT pacing is difficult to achieve.
In this article, we will review the anatomy of the RVOT and discuss the importance of standard radiographic views and the 12-lead electrocardiogram in aiding lead placement. We will also describe a method utilizing a novel stylet shape, whereby a conventional active-fixation, stylet-driven lead can be easily and reliably deployed onto the RVOT septum.
右心室心尖部起搏与左心室功能的长期不良影响相关。这激发了人们对替代起搏部位的兴趣，尤其是右心室流出道（RVOT）的间隔面。然而，人们普遍认为间隔部RVOT起搏难以实现。
在本文中，我们将回顾RVOT的解剖结构，并讨论标准影像学视图和12导联心电图在辅助导线置入中的重要性。我们还将描述一种利用新型探针形状的方法，通过该方法，传统的主动固定、探针驱动导线可以轻松、可靠地放置在RVOT间隔上。
