摘要

急性冠状动脉左主干闭塞是急性冠状动脉综合征最严重的形式之一。除了典型的心电图改变外，重要的是及时识别非典型的改变，并及时进行血运重建治疗。通过对具体病例的分析，本工作发现aVR和aVL导联st段抬高，伴新出现的双束阻滞，不能排除病理性，但胸导联无st段偏曲，高度提示LMCA完全闭塞的罕见心电图表现。另一方面，次全闭塞代表一个更罕见的情况。

A Rare Case of Atypical Electrocardiogram Changes in Subtotal Occlusion of the Left Main Coronary Artery

Acute occlusion of the left main coronary artery (LMCA) is one of the most severe forms of acute coronary syndrome. Besides the typical electrocardiogram changes, it is important to promptly recognize atypical changes and hasten revascularization therapy without delays. By analyzing specific cases, this work revealed that ST-segment elevation in aVR and aVL leads, accompanied by newly developed bifascicular block that cannot be ruled out as pathological, but without ST-segment deviation in the chest leads, highly indicates a rare electrocardiographic manifestation of complete occlusion of the LMCA. On the other hand, subtotal occlusion represents an even rarer scenario.

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.
