A 38-year-old obese woman presented with recurrent polymorphic ventricular tachycardia secondary to persistent hypokalemia necessitating more than 40 DC shocks. All endocrine investigations for hypokalemia were negative with impression of "mysterious hypokalemia." On repeated inquiry, a hidden history of licorice use was elicited causing persistent hypokalemia. The case highlights a life threatening complication of licorice use. In addition, it reiterates the importance of repeated history taking in a patient with undiagnosed hypokalemia and torsade de pointes which avoided a device therapy.
一名38岁肥胖女性因持续性低钾血症继发反复多形性室性心动过速，需要接受40多次直流电除颤。所有针对低钾血症的内分泌检查均为阴性，诊断为“不明原因低钾血症”。经反复询问，发现其有隐匿的甘草使用史，导致持续性低钾血症。该病例突出了甘草使用的一种危及生命的并发症。此外，它重申了对未确诊低钾血症和尖端扭转型室速患者反复询问病史的重要性，这避免了器械治疗。
