Gintonin increases IKs of guinea pig ventricular myocytes. (A) Time course of changes in the amplitude of the IKs tail during applications of gintonin (3 μg/ml). (B) I–V relationships obtained before and after application of gintonin. Currents were elicited by voltage steps from −30 mV to +70 mV with a subsequent step to −30 mV for the tail current. Representative recordings are shown in the inset. Data are represented as mean ± S.E. (n = 8). *p < 0.05 versus control condition (paired t test)
