    摘要: The subject invention includes mutant voltage-gated ion channels that are open over a wide range of potential differences across membranes. The present invention also includes methods of use such mutant voltage-gated ion channels in cells with highly negative potential differences across their membranes. One preferred mutant voltage-gated ion channel is a channel with a mutation at the residue homologous to P513 in Kv1.5 and at least one mutation at one of the residues homologous to R400, R403, and R409 in Kv1.5.

    摘要: Methods, compositions, dosing regimes, and routes of administration for the treatment or prevention of arrhythmias. In these methods, early afterdepolarizations and prolongation of QT interval may be reduced or eliminated by administering ion channel modulating compounds to a subject in need thereof. The ion channel modulating compounds may be cycloalkylamine ether compounds, particularly cyclohexylamine ether compounds. Also described are compositions of ion channel modulating compounds and drugs which induce early afterdepolarizations, prolongation of QT interval and/or Torsades de Pointes.
