Ion channel trafficking
WebIon channel trafficking: A new therapeutic horizon for atrial fibrillation. Atrial fibrillation (AF) is a common cardiac arrhythmia with potentially life-threatening complications. Drug therapies for treatment of AF that seek long-term maintenance of normal sinus rhythm remain elusive due in large part to proarrhythmic ventricular actions.
