Supernormal excitability and conduction.
The authors examine circumstances in which supernormality causes specific electrocardiographic events. True supernormal conduction is much more common than previously thought. A complete scanning of the cardiac cycle in patients with phase 3 BBB or with second-degree or advanced infranodal AV block would reveal that a much larger number of cases of supernormal conduction would be uncovered.
