Using moxifloxacin and terfenadine, which are known to induce benign and malignant QT interval prolongation, respectively, we analysed whether halothane-anaesthetized microminipigs are an appropriate model for assessing the risk of drug-induced long QT syndrome. Moxifloxacin (0.03, 0.3 and 3 mg/kg) and terfenadine (0.03, 0.3 and 3 mg/kg) were intravenously(More)
We pharmacologically characterized microminipigs as an in vivo experimental model by assessing cardiovascular effects of pilsicainide, verapamil and E-4031, which can preferentially inhibit cardiac Na+, Ca2+ and K+ channels, respectively. Intravenous infusion of 1 mg/kg of pilsicainide (n = 4), 0.1 mg/kg of verapamil (n = 4) and 0.01 followed by 0.1 mg/kg(More)
Anti-atrial fibrillatory and proarrhythmic potentials of amiodarone were simultaneously analyzed by using the halothane-anesthetized beagle dogs (n = 4) in order to begin to prepare standard protocol for clarifying both efficacy and adverse effects of anti-atrial fibrillatory drugs. Intravenous administration of 0.3 mg/kg of amiodarone hydrochloride(More)
A 14 month-old intact microminipig, weighing 8 kg, showed ST-segment elevation in A-B lead electrocardiogram during cardiac catheterization followed by ventricular tachycardia, which degenerated into ventricular fibrillation. Although a direct current defibrillation of 360 J was applied, ventricular tachycardia re-occurred for another 2 times and the direct(More)
