Refralon Versus Amiodarone for Cardioversion of Paroxysmal Fibrillation and Atrial Flutter

"Patients in this group will receive intravenous amiodarone according to the following scheme:~1. administration of 5 mg/kg body weight of amiodarone diluted in 250 ml of 5% glucose solution intravenously for 20-60 minutes, depending on the tolerability of the drug.~2. if there is no effect (recovery of SR did not occur within 60 minutes from the start of the drug administration), continue the infusion of amiodarone intravenously at a dose of 100 mg/hour until a total dose of 1200 mg is reached."

"Patients in this group will receive intravenous refralon according to the following scheme:~1. the introduction of a 0.1% solution of refralon at a dose of 5 μg per 1 kg of body weight, diluted in 20 ml of saline intravenously for 2-3 minutes;~2. in the absence of effect (SR recovery did not occur), after 15 minutes, repeated intravenous administration of a 0.1% solution of refralon at a dose of 5 μg per 1 kg of body weight (total dose of the drug 10 μg / kg of body weight);~3. in the absence of effect (SR recovery did not occur), after 15 minutes, the next intravenous injection of a 0.1% solution of refralon at a dose of 10 μg per 1 kg of body weight (total dose of the drug 20 μg / kg of body weight);~4. in the absence of effect (recovery of SR did not occur), after 15 minutes, repeated intravenous administration of a 0.1% solution of refralon at a dose of 10 μg per 1 kg of body weight. Thus, the maximum total dose of the drug will be 30 μg/kg of body weight."
