The effect of 10 μM dronedarone on the rapid component of the delayed rectifier outward potassium current (IKr) in single dog ventricular myocyte. (A) shows original recordings from a representative experiment. (B) indicates the voltage current relation before (○) and after (•) dronedarone (10 μM for 3–5 minutes) superfusion in an average of six cells. Bars indicate±s.e.mean.
