title: [Ventricular hyperkinetic arrhythmias and circulatory arrest in idiopathic isolated complete atrioventricular block. Description of a clinical case].
abstract: Here we report on the case of a patient with idiopathic complete AV block and ventricular ectopic beats in basal state. The patient had been asymptomatic until the age of 50 and then suddenly began to suffer from relapsing episodes of syncope, related to "Torsade de Pointe" and Ventricular Fibrillation (hypokalaemia was present at the same time). We deal with the prognostic significance of ventricular ectopic beats and we make the hypothesis that hyperkinetic ventricular arrhythmias play a role in the origin of the symptoms of patients with congenital or idiopathic complete AV block. Finally, we discuss the limits of the therapeutic effectiveness of permanent pacing in these cases.
