Feasibility and Safety of IV Sotalol Administered as a Loading Dose to Initiate Oral Sotalol Therapy

The hypothesis to be tested is that the intravenous loading regimen followed by oral sotalol administration 4 hours after the conclusion of the IV infusion (every 12 hours thereafter) will result in sotalol peak concentrations at the end of IV loading dose (IV to oral loading) which are comparable to the steady state and maximum QTc seen on Day 3 after the last in-hospital oral dose.
