title: [Study of flecainide in the treatment of ventricular arrhythmia].
abstract: The effect of flécaïnide (new class I antiarrhythmic) on ventricular rhythm troubles was studied in 24 patients using Holter's method. The following results were obtained. For ventricular tachycardia, two cases of suppression, three cases of distinct reduction in the number and duration of attack and one failure were recorded. For single ventricular extrasystoles, doublets and triplets, nine very good results (80 to 100 per cent reduction of arrhythmia) and four 50 to 80 per cent reductions in ventricular prematurity were obtained. Results were uncertain in two patients as the disappearance of extra-systoles was not followed by relapse after termination of treatment. There were three failures. A twenty-fifth patient was treated with flécaïnide IV followed by oral administration with uncertain results. Undesirable effects are infrequent and are often characterized by sinusal bradycardia. Blurred vision and paraesthesia were encountered. The principal biological parameters remained unchanged.
