The diagnosis of advanced interatrial block (A-IAB) is done by surface ECG analysis when the P-wave ≥120 ms with biphasic (±) morphology in leads II, III and aVF. In this brief communication, we advance a new concept involving atypical patterns of A-IAB due to changes about the morphology or duration of the P-wave. It remains to be determined its real prevalence in different clinical scenarios, and whether these atypical ECG patterns should be considered as predictors of atrial fibrillation/stroke.
当在II、III和aVF导联中P波≥120毫秒且呈双相(±)形态时,通过体表心电图分析来诊断晚期房内阻滞(A-IAB)。在这篇简短的通讯中,我们提出了一个新的概念,即由于P波形态或时限的改变而导致的A-IAB非典型模式。其在不同临床场景中的实际患病率以及这些非典型心电图模式是否应被视为房颤/中风的预测指标仍有待确定。
