We report the case of a 23-year-old male with thalassemia major who developed long QT and continuous ventricular tachycardia (VT). Electrocardiography, echocardiography, and cardiac magnetic resonance imaging (MRI) were used for diagnosis and risk stratification. VT causes and treatments are presented and discussed. Ventricular arrhythmia can be treated by normalizing QT interval with high-dose beta-blocker therapy. However, MRI-compatible internal cardiac defibrillator implantation was performed due to the high risk in this patient.
我们报告了一例23岁重型地中海贫血男性患者，该患者出现了长QT间期和持续性室性心动过速（VT）。采用心电图、超声心动图和心脏磁共振成像（MRI）进行诊断和风险分层。介绍并讨论了室性心动过速的病因及治疗方法。室性心律失常可通过大剂量β受体阻滞剂治疗使QT间期正常化来进行治疗。然而，由于该患者风险较高，故进行了磁共振成像兼容型体内心脏除颤器植入术。
