ASL = anteroseptal line (line between mitral annulus and right superior
pulmonary vein); AT = atrial tachycardia; AVNRT = atrioventricular nodal
reentrant tachycardia; CTI = cavotricuspid isthmus; IVC = inferior vena
cava; LA = left atrium; LIPV = left inferior pulmonary vein; LSPV = left
superior pulmonary vein; MAL = modified anterior line (line between
mitral annulus and left superior pulmonary vein); PVI = pulmonary vein
isolation; RIPV = right inferior pulmonary vein; RSPV = right superior
pulmonary vein; STD = spatiotemporal dispersion; SVC = superior vena
cava.
* Sites with spatiotemporal dispersion plus non-continuous fractionation
were only mapped if no rotors were present or if rotor ablation was
ineffective.
† Spontaneous conversion from AF to stable AT occurred after rotor
mapping in the left atrium was completed (no rotors were found).

without recurrences of atrial arrhythmias.
