Figure 6.
The impact of IKs and ICa,L phosphorylation on the action potential of canine ventricular epicardium in the presence of CQ and AZM. The effect of CQ 5 μM in combination with AZM 20 μM in the presence of ISO-induced IKs and ICa,L phosphorylation is shown in solid green lines. The green dashed lines represent the effect of CQ 5 μM in combination with AZM 20 μM in the absence of ISO-induced IKs and ICa,L phosphorylation.
