Clockwise vs counterclockwise atrial flutter
WebCounterclockwise (CCW) typical flutter This is the most frequent form of AFL. The mechanism is a macroreentrant circuit confined within the RA, with a descending wavefront in the lateral wall and an ascending wavefront on the septum with passive activation of the left atrium (LA). WebObjective: The purpose of this study is to determine the reliability of activation sequence mapping in assessing the presence of bidirectional conduction block (BCB) in typical atrial flutter (AFL) ablation.
