Abstract

Interatrial block (IAB) is a conduction disorder linked to atrial fibrillation (AF) and ischemic stroke. Intermittent IAB, often triggered by premature atrial complexes (PACs), may precede AF and increase thromboembolic risk. We present a case of embolic stroke of undetermined source (ESUS) with intermittent partial IAB detected on ECG. Serial ECGs and Holter monitoring were analyzed. Intermittent partial IAB with dynamic P-wave changes was observed. No AF or alternative embolic source was identified. Intermittent IAB may indicate atrial vulnerability in ESUS. Recognizing subtle ECG changes could aid risk stratification and stroke prevention.

复发性短暂性脑缺血发作患者的间歇性房间传导阻滞

心房传导阻滞（IAB）是一种与心房颤动（AF）和缺血性脑卒中相关的传导障碍。间断性内耗，通常由早发性心房复合体（PACs）触发，可能先于房颤并增加血栓栓塞风险。我们报告了一例来源不明的栓塞性中风（ESUS），心电图上检测到间歇性部分IAB。分析连续心电图和动态心电图监测。间歇性局部IAB伴动态p波变化。未发现房颤或其他栓塞源。间歇性IAB可能提示esu患者心房易损。识别细微的心电图变化有助于风险分层和中风预防。

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
