Isoproterenol attenuated J-point elevation and APD heterogeneity induced by ACh and ajmaline. (A). PseudoECG during sinus rhythm at baseline, after cumulative addition of ACh and ajmaline and isoproterenol. (B). Representative APD80 maps at sinus rhythm at baseline, after cumulative addition of ACh and ajmaline and isoproterenol. (C). Corresponding overlapped Vm traces of locations 1 (red), 2 (black) and 3 (green) in (B). (D). ΔAPD80 maps before and after ACh+ajmaline and before and after isoproterenol.
