The Role of Adenosine in Pulmonary Vein Isolation: A Critical Review

Figure 1

Microelectrode recordings before and after pulmonary vein isolation in a PV without dormant conduction (upper panel) and in a PV with dormant conduction (lower panel). S: stimulus artifacts with no response. Dotted line: excitability threshold at −50 mV (adapted from Datino et al. [7]).
