Astract: The aim of this work was to investigate whether the inward rectifying current Ik1 participates in the response of the myocardium to metabolic inhibition and to evaluate quantitatively the contribution of IK,ATP to the increase in outward current elicited by metabolic inhibition. The work was carried out on freshly isolated rabbit ventricular myocytes at room temperature using the patch clamp technique in the whole cell configuration. Steady-state currents (Iss) were measured at the end of 400 ms long pulses. The results showed that the current vs voltage relationship in control conditions varied with [K]o, 50 /µM Ba2+ abolished inward rectification of Iss and 30 µM glibenclamide had no effect on Iss in control conditions.
