[Holter analysis of ventricular arrhythmias and its treatment with propafenone]

We studied 20 patients with ventricular premature beats. All of them underwent 16-24 hs Holter monitoring before and during propafenone treatment at an average dosage of 600 mgs P.O. We observed 86% decrease in the ectopic beats. In two cases there was a complete abolition of the ventricular beats. The Lown's type 3 ventricular beats had a 50% reduction. The were not significant modifications of the heart rate of blood pressure. There were not significant side effects. We consider propafenone as a potent agent for the treatment of ventricular ectopic beats.
