[K+]o dependence of hypokalemia-induced VT/VF in isolated rabbit hearts, without or with dofetilide. When [K+]o was lowered, the incidence of VT/VF within 90 minutes progressively increased to 100% at 2.0 and 1.0 mmol/l (black circles). Dofetilide (1 μmol/l) shifted the dose-response curve to the right. Reproduced with permission from Pezhouman et al.2
