  • Title: Induction and termination of afterdepolarizations and triggered arrhythmias by drugs in cat heart in vivo.
    Author: Xie JT, Li CL.
    Journal: Methods Find Exp Clin Pharmacol; 1992 Jun; 14(5):347-54. PubMed ID: 1513189.
    Abstract:
    In order to investigate some anti-triggered arrhythmic drugs, the afterdepolarizations and triggered arrhythmias were induced by cesium chloride and the monophasic action potentials of the left ventricular epicardium in vivo were recorded by using a contact electrode in 58 cats. These results suggested that a) early- and afterdepolarizations, oscillatory afterpotentials and some different kinds of triggered arrhythmias were induced by cesium chloride, b) sodium valproate (150 mg/kg) could prevent CsCl-induced triggered activities, c) lidocaine (5 mg/kg), ethmozine (5 mg/kg) and sodium valproate (150 mg/kg) could terminate CsCl-induced ventricular tachycardias. The present studies provide a basically experimental evidence for treating triggered arrhythmias in clinic.
