本文报导两例中隔支传导阻滞(SFB)的临床及心电图表现。患者均为典型的冠心病患者。发作心绞痛和/或心肌梗塞形成时,伴有胸前导联一系列畸形多变的QRS波形。作者复习了文献中各家对SFB时心电图表现的不同报导,结合自身的经验指出:SFB的心电图特征可能为右胸导联表现多种畸形的QRS波形;其主要病理可能在左冠脉主干和/或左前降支近端。鉴于本病提示心绞痛的不稳定性,作者提出,可作V_3高一肋间导联的心电监护,以利于诊断,同时讨论了积极治疗的措施。
This article reports the clinical and electrocardiographic findings of septal branch block (SFB) in two cases. Patients are typical of patients with coronary heart disease. Angina pectoris and / or myocardial infarction are associated with a series of abnormal QRS waveforms in the precordial leads. The authors reviewed various reports in the literature on SFB ECG reports, combined with their own experience that: SFB ECG characteristics may be the right chest leads show a variety of abnormal QRS waveform; its main pathology may be in the left coronary artery and / Or proximal left anterior descending artery. In view of the instability of the disease prompted angina pectoris, the authors suggest that ECG monitoring can be used for V_3 high intercostal lead to facilitate the diagnosis, and discussed the active treatment measures.
