Abstract
Novel heterocyclo compounds useful as inhibitors of potassium channel function (especially inhibitors of the Kv1 subfamily of voltage gated K+ channels, especially inhibitors Kv1.5 which has been linked to the ultra-rapidly activating delayed rectifier K+ current IKur), methods of using such compounds in the prevention and treatment of arrhythmia and IKur-associated conditions, and pharmaceutical compositions containing such compounds.
