Figure 2. In the basic
pattern of atrial activation during AF, concurrent multiple
PV focal activations and fibrillatory conduction are the dominant
mechanism in AF. Extremely rapid activations in the PV and a
progressive conduction delay or block in the pathway from the
focus to the right atrium and in the lateral right atrium causes
an irregular and complex right atrial activation, resulting
in coexisting multiple wavelets.
