Abstract: In this paper we report the arrhythmias recorded on basal ECG, on Holter monitoring or on exercise test, in 32 pts affected by arrhythmogenic right ventricle (ARV). A sustained ventricular tachycardia (VT) was present in 11 pts a non sustained VT in 15 pts, a slow VT in 2 pts, a ventricular fibrillation (VF) in 3 pts and both sustained VT and VF in 1 pt. All but 1 case of sustained VT showed a LBBB like pattern. The heart rate during VT ranged between 170 and 280 beats/min. The frontal axis of the VT showed a wide range of deviation. Among non sustained VT, 9 cases had LBBB like pattern and 6 cases had polymorphic configuration. The 2 cases of slow VT showed LBBB like pattern with right axis deviation. A comparison between ventricular arrhythmias and RV impairment was made. The data obtained suggest that the effort plays an important role in the induction of VT in pts with localized RV impairment. In conclusion a wide spectrum of ventricular tachyarrhythmias is present in the ARV. Probably the RV arrhythmogenic zones and the electrophysiological mechanism causing the arrhythmias are various.
