we conclude that in our population of patients without organic heart disease , bundle branch re-entry is a frequent finding and is not related to ventricular arrhythmias , that intraventricular re-entry is less frequent and although it is associated with a higher incidence of ventricular tachycardia or fibrillation , it is a poor predictor of these arrhythmias in this study population .
