 right-bundle-branch block morphology and positive concordance throughout the chest leads,
 inferior axis and at least one of the following:

 1. >2000 isolated VEB/24h

 2. symptomatic monomorphic ventricular tachycardia

 3. left ventricular disfunction supposed to be due to tachycardia-induced cardiomyopathy

 Exclusion Criteria:
