in patients with recurrence of arrhythmia compared with asymptomatic patients , administration of amiodarone caused a longer ventricular effective refractory period ( 296 +/- 8 versus 271 +/- 7 ms , p less than 0.05 ) and a greater change in corrected qt [ qtc ] interval ( 90 +/- 18 versus 44 +/- 9 ms , p less than 0.02 ) , but no difference in the decrease in premature ventricular complexes after treatment with amiodarone .
