Activation maps for patient AX4.
(A) Noninvasively imaged AFL reentry circuit from one single beat. Solid black lines represent propagation wavefronts in RA. (B) Average AFL reentry circuit. (C) CARTO activation map. AFL = Atrial flutter; IVC = Inferior vena cava; LA = Left atrium; MA = Mitral annulus; RA = Right atrium; SVC = Superior vena cava; TA = Tricuspid annulus.
