Increase of effective refractory period in New Zealand white rabbit assessed as maximum change in QT interval at 0.1 and 1 umol/kg/min for 15 mins infusions
Unbound steady state plasma concentration in New Zealand white rabbit assessed as concentration required to 20% change in atrium effective refractory period at 0.1 and 1 umol/kg/min for 15 mins infusions
