[Definitions of second degree atrioventricular block. An exercise in logic in clinical electrocardiography].
Second degree atrioventricular block has received different definitions which make it difficult for physicians to interpret certain cases. This review of the literature provides an accurate definition of the criteria of Mobitz I and Mobitz II atrioventricular block, and proposes simple diagnostic methods based on conventional electrocardiography. The importance of the definitions is underlined and the consequences in terms of permanent cardiac pacing are emphasised.
