房间传导阻滞（IAB; P波持续时间≥ 110 ms），代表心房之间的传导延迟，是一种流行性传导异常，在临床实践中经常被低估。尽管它在医学文献中有全面的文献记载，但它仍然没有得到足够的重视，在大多数心脏病学教科书中也没有充分描述和讨论。IAB可以是不同程度的，并根据P持续时间的程度及其形态进行分类。它可以转化为更高程度的块，也可以表现为短暂的。IAB可能是各种房性心律失常（特别是房颤）的先行或致病风险因素，也与各种其他临床异常相关，包括左心房扩张和血栓栓塞（包括栓塞性卒中和肠系膜缺血）。IAB当然值得更多的关注和前瞻性的研究，需要制定一个标准的共识，适当的管理策略。
Interatrial block (IAB; P-wave duration ≥ 110 ms), which represents a delay in the conduction between the atria, is a pandemic conduction abnormality that is frequently underappreciated in clinical practice. Despite its comprehensive documentation in the medical literature, it has still not received adequate attention and also not adequately described and discussed in most cardiology textbooks. IAB can be of varying degrees and classified based on the degree of P-duration and its morphology. It can transform into a higher degree block and can also manifest transiently. IAB may be a preceding or causative risk factor for various atrial arrhythmias (esp. atrial fibrillation) and also be associated with various other clinical abnormalities ranging from left atrial dilation and thromboembolism including embolic stroke and mesenteric ischemia. IAB certainly deserves more attention and prospective studies are needed to formulate a standard consensus regarding appropriate management strategies.
