Abstract
Under certain conditions, the presence of two anatomically or functionally separate pathways can be detected from evidence provided by the surface (scalar) electrocardiogram. Dual pathways with differing physiologic characteristics result in asynchronous conduction. Such asynchrony may present electrocardiographically as (1) atrioventricular nodal reentry, (2) echo beats, (3) the appearance of two different PR or RP intervals, and (4) dual ventricular response. Dual pathways manifesting as echo beats, two different PR/RP intervals, or dual ventricular response are discussed in this chapter. Atrioventricular nodal reentry is discussed at length in Chapter 13.
