This figure shows the classification of atrial arrhythmia in this study.
Fifty-nine atrial arrhythmias were divided into 49 mappable ATs and 10
AF. Mappable ATs are divided into 37 macroreentant-AT and 12
non-macroreentant-AT. Macroreentant-ATs are divided into 22 M-AFL, 11
T-AFL, and 4 RA macroreentant-ATs. Non-macroreentant-ATs are divided
into 4 septal, 4 LAA, 2 LA, and 2 RA focal ATs. Each ATs are stated
whether these are gap-related or not.
AF, atrial fibrillation; AT, atrial tachycardia; LA, left atrium; LAA,
left atrium appendage; M-AFL, peri-mitral atrial flutter; RA, right
atrium; T-AFL, cavotricupid isthmus dependent atrial flutter.
