【摘要】：正患者男、45歲,赴美國看望讀書的女兒三周,回國后感到疲勞、頭暈,關(guān)節(jié)和肌肉疼痛。體檢發(fā)現(xiàn)下肢環(huán)狀紅斑,心電圖見圖1。試題內(nèi)容本例患者房室阻滯的部位為A.房室結(jié)(AV node);B.希氏束內(nèi)(Intra-His);C.希氏束以遠(yuǎn)(Infra-His);D.心室肌內(nèi)(Ventricular Myocardium)正確答案:A答案分析1.二度房室阻滯本例心電圖的最大特征是全幀心電圖一直持續(xù)為2:1房室阻滯,體表心電圖對房室阻滯診斷的優(yōu)勢是對阻滯程度能迅速判斷,例如本幀心電圖應(yīng)診斷為二度房室阻滯。而心電圖診斷房室阻滯的部位卻
[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.
