The case report of a patient with an ECG pattern of intermittent left bundle-branch block, presenting inverted and symmetric ("coronary") T waves in leads V1 to V3 during periods of normal intraventricular conduction, is presented. The patient was followed up for eight years during which time no relevant symptoms appeared while extensive noninvasive investigations repeatedly failed to reveal any organic basis for the ECG changes. It is stressed that inverted, symmetric T waves in right-sided chest leads may be encountered in young, otherwise healthy subjects with intermittent left bundle-branch block during periods of normal intraventricular conduction. Knowledge of this fact is important in order to avoid iatrogenic cardiac invalidism in such cases.
本文报告了一例间歇性左束支传导阻滞心电图模式的患者，在正常心室传导期间，V1至V3导联出现倒置且对称（“冠状”）T波。该患者随访了八年，在此期间未出现相关症状，同时广泛的无创检查反复未能揭示心电图改变的任何器质性基础。强调在年轻、其他方面健康且有间歇性左束支传导阻滞的受试者中，在正常心室传导期间右侧胸导联可能出现倒置、对称的T波。了解这一事实对于避免此类病例中的医源性心脏残疾很重要。
