Raza Askari,Naglaa Keriakos,Sunil K Jha,Rami Khouzam*

We present the case of a patient with ischemic cardiomyopathy using quinine as a remedy for leg cramps. A wearable cardioverter defibrillator (WCD) (LifeVest, Zoll Medical Corporation) recorded a sustained episode of polymorphic ventricular tachycardia resulting in syncope. Electrolyte concentrations were normal while QT interval was prolonged which improved after cessation of quinine and grapefruit juice.
