英文原文: ECG Characteristics of HCM The ECG is abnormal in 90% of symptomatic patients and is characterized in the following list. 1. LVH by voltage criteria. 2. Marked ST-T wave abnormalities and T-wave inversion in lateral precordial leads (coved ST-segment elevation in lateral chest leads). 3. Deep, narrow Q waves in aVL, and V6 (≥40 ms). 4. Diminished R wave in lateral precordial leads. 5. LAE. 翻 譯 肥厚型心肌病的心電圖特征 90%的有癥狀患者的心電圖是不正常的,其特征有以下幾點。 1、符合左室肥厚的電壓標準。 2、側(cè)壁導(dǎo)聯(lián)明顯的ST-T異常和T波倒置(側(cè)壁導(dǎo)聯(lián)ST段抬高)。 3、AVL,V6導(dǎo)聯(lián)可見深而窄的Q波(≥40 ms)。 4、側(cè)壁導(dǎo)聯(lián)R波減低。 5、左房擴大。 英文原文: Abnormal Q waves (Q wave >3mm in depth and/ or >40ms in athletes in 2 leads except aVR) are one of the most common ECG abnormalities in young patients with HCM. Interestingly, the Q waves may disappear with increasing age, especially when concentric LVH develops.In about 6% of patients with clinical presentation and Echo evidence of HCM,the ECG may be normal upon presentation. This subset of patients appears to have a less severe phenotype with better cardiovascular outcome. 翻 譯 異常Q波(Q波深度>3mm和/或運動員除aVR導(dǎo)聯(lián)外2個導(dǎo)聯(lián)Q波時限>40ms)是肥厚型心肌病年輕患者中最常見的心電圖異常之一。有趣的是,隨著年齡的增長,尤其在離心性左室肥厚的發(fā)展過程中,Q波可能會消失。有臨床表現(xiàn)且超聲符合肥厚型心肌病患者中,約6%的心電圖可能是正常的,心電圖可能是正常的。這組患者似乎有不太嚴重的表型,心血管預(yù)后較好。(翻譯:王世聰;校對:何樹楠) 不做就圖論圖,只做透徹解讀! 病因甄別、合并疾病、 體格檢查、可能診斷、治療策略…… 一份臨床綜合的心電圖說明書! “讀心有術(shù)”欄目每天與您相約! |
