OBJECTIVES: In order to study the efficiency of oral dose of propafenone in preventing childhood supraventricular tachycardias, we have treated 38 children without left ventricular dysfunction.
METHODS: The mean age has been 8 +/- 4.7 years old. All of them had suffered at least two episodes of supraventricular tachycardia, and eleven had undergone a previous antiarrhythmic treatment. The initial dose of propafenone has been 6.5 +/- 2.1 mg/kg/24 h (in 3 doses), which has been increased in case of inefficacy.
RESULTS: We have not advised neither side-effects, nor proarrhythmic effects, during a follow-up of 13 +/- 6 months. Propafenone has been efficient in preventing supraventricular tachycardias in all patients. The initial dose has been efficient in 17 patients, and we have increased the initial dose up to 11.1 +/- 3.7 mg/kg/24 h in 21 patients. The mean effective dose has been 8.9 +/- 3.6 mg/kg/24 h. We stopped treatment in 14 patients after been 6 months without supraventricular tachycardias.
CONCLUSION: From our study, we conclude that propafenone has been efficient in preventing supraventricular tachycardias in childhood with a dose of 8.9 mg/kg/24 h. We have not found side-effects.
