The purpose of this registry is to collect data among patients and centers using IV sotalol loading for initiation or dose titration in the treatment of atrial arrhythmias, in order to fill the above knowledge gaps.


  1. Adults age 18 years and older
  2. Eligible for the use of elective intravenous sotalol loading to treat atrial arrhythmias, per the treating clinician
  3. IV sotalol infusion started for the treatment of atrial arrhythmias, in the setting of initiation or dose titration of chronic sotalol therapy
  4. Elective hospital admission primarily for loading with intravenous sotalol with/without cardioversion, with no other planned therapy or procedures
