Previous studies showed that myocardial edema correlates with dynamic T-wave inversion and QTc prolongation in a variety of acute cardiovascular diseases including takotsubo syndrome (TTS). We reported the case of a patient with "atypical" (mid-ventricular) TTS showing a unique pattern of diffuse T-wave inversion that spared only the apical precordial leads V3-V4. Cardiac magnetic resonance (CMR) showed myocardial edema involving all mid-ventricular segments but not the apex. Both ECG and CMR normalized at follow-up evaluation. This case further reinforces the theory of an association between presence and regional distribution of acute myocardial inflammation and dynamic repolarization changes.
先前的研究表明，心肌水肿与动态 T 波倒置和 QT 间期延长有关，涉及多种急性心血管疾病，包括心尖球囊综合征（TTS）。我们报告了一例“非典型”（中隔室）TTS 患者，其表现为一种独特的弥漫性 T 波倒置模式，仅心前区导联 V3-V4 不受累。心脏磁共振（CMR）显示心肌水肿累及所有中隔室节段，但不累及心尖。心电图和 CMR 在随访评估时均恢复正常。该病例进一步证实了急性心肌炎症的存在及其区域性分布与动态复极变化之间的关联。
