Conclusions
The focal activations may represent the specific characteristics and electrical features of the AF driver, which may be different from conventional AF substrates, such as CFAE or LVA. DFAs identified using the novel mapping algorithm may play an important role in the AF process and framework of AF maintenance and may be an attractive therapeutic target for AF drivers associated with improved procedural outcomes.
