Abstract：
Idiopathic fascicular ventricular tachycardia (IFVT) is an arrhythmia that occurs in a structurally normal heart and may present with sudden onset in a healthy individual. We present the case of a 10-year-old female child, with no pertinent medical history, who complained of palpitations and shortness of breath, which was followed by suicidal ideations. On presentation to the ER, tachycardia was noted with other vital signs within normal limits. Labs were unremarkable. EKG showed wide-complex tachycardia with right bundle branch block and left superior axis, consistent with idiopathic left ventricular fascicular tachycardia. The echocardiogram showed normal cardiac structure. She was transferred to the cardiovascular care unit and intravenous verapamil was given with the resolution of symptoms and reversal of tachycardia. She remained hemodynamically stable and was subsequently discharged on oral verapamil. This case report is aimed at raising awareness of the different ways IFVT can manifest, aiding physicians to easily recognize the zebra among the horses.
摘要：
特发性束状室性心动过速（IFVT）是一种心律失常，发生在结构正常的心脏中，可能在健康个体中突然发作。我们介绍了一个10岁女童的案例，没有相关病史，抱怨心悸和呼吸急促，随后是自杀意念。在向急诊室介绍时，其他生命体征均在正常范围内。实验室并不引人注目。心电图显示宽复杂性心动过速，右束支传导阻滞，左上轴，符合特发性左心室束状心动过速。超声心动图显示心脏结构正常。她被转移到心血管监护病房，并静脉注射维拉帕米，以缓解症状并逆转心动过速。她保持血液动力学稳定，随后口服维拉帕米出院。本病例报告旨在提高人们对IFVT表现的不同方式的认识，帮助医生轻松识别马中的斑马。
