Fig. 2

A An ultra-high resolution activation map revealed a clockwise roof-dependent AT with slow conduction on the LA posterior roof (TCL = 231 ms) (left panel). The white arrows show the propagation of the activation. A voltage map shows scar on the LA posterior roof (right panel). B The valley (green curtain, white arrow) on the global activation histogram (skyline, blue square) corresponds to the isthmus of the AT (highlighted area). Please note the straight CS activation pattern (yellow square). LAA left atrial appendage, LI(S)PV left inferior (superior) pulmonary vein, RI(S)PV right inferior (superior) pulmonary vein, TCL tachycardia cycle length
