【摘要】：正患者男、45岁,赴美国看望读书的女儿三周,回国后感到疲劳、头晕,关节和肌肉疼痛。体检发现下肢环状红斑,心电图见图1。试题内容本例患者房室阻滞的部位为A.房室结(AV node);B.希氏束内(Intra-His);C.希氏束以远(Infra-His);D.心室肌内(Ventricular Myocardium)正确答案:A答案分析1.二度房室阻滞本例心电图的最大特征是全帧心电图一直持续为2:1房室阻滞,体表心电图对房室阻滞诊断的优势是对阻滞程度能迅速判断,例如本帧心电图应诊断为二度房室阻滞。而心电图诊断房室阻滞的部位却
[Abstract]:A 45-year-old man, who visited her daughter in the United States for three weeks, felt tired, dizziness, joint and muscle pain after returning home. A physical examination revealed ringlike erythema in the lower extremities. Electrocardiogram 1. The location of atrioventricular block in this case is A. AV nodesia B. Intra-Hischus bundles in the Hickers tract. The correct answer to the question: 1. Second degree atrioventricular block the largest electrocardiogram in this case. 1. Analysis of the largest electrocardiogram in this case. (2) atrioventricular block in patients with atrioventricular block (AVB) in the second degree of atrioventricular block (AVB) is the largest electrocardiogram (ECG) in the second degree of atrioventricular block. The sign is that the whole electrocardiogram continues to be 2: 1 atrioventricular block, The advantage of body surface electrocardiogram in diagnosing atrioventricular block is that it can judge the degree of atrioventricular block quickly. For example, this electrocardiogram should be diagnosed as second degree atrioventricular block.
