Clinical examination should not be forgotten when assessing the level of 2/1 AV block

The authors underline the importance of carrying out a simple clinical examination to assess the level of two-to-one auriculoventricular block before any invasive electrophysiological procedures are performed. Clinical examination can indeed easily distinguish between the two different prognostic entities, represented by nodal and infra-nodal atrioventricular block. This initial evaluation of the severity of conduction disorders, as soon as the patient arrives at the emergency department or attends a consultation, may be greatly helpful in selecting the most appropriate management of those patients.
