Effects of Ro20-1724 and IBMX on ICa in a rat ventricular myocyte. Each symbol corresponds to a measure of ICa at 0 mV obtained every 8 s. The cell was first superfused with control Cs+ Ringer solution and then exposed to the drugs during the periods indicated by the solid lines. 0.3 μM Ro20-1724 had no effect on ICa, while application of 100 μM IBMX produced a strong and reversible stimulation of ICa The individual current traces shown on the upper part were obtained at the times indicated by the corresponding letters in the bottom graph. The dotted line indicates the zero current level.
