    Aim: The aim of this study is to determine the effect of exogenous phosphocreatine (PCr) with different concentration on transient outward potassium (Ito), natrium (INa) and L-type calcium (ICa,L) current in ischemic ventricular cells of rat and to explore its role in the treatment of ischemic heart disease. Methods: Ventricular cells were isolated enzymatically from left ventricular of rat. Peak Ito, INa and ICa,L current were recorded using patch clamp techniques in the whole-cell configuration in the setting of cells superfused with normal Tyrode solution, simple simulated ischemic solution (SI), ischemic solution containing PCr with concentration of 5, 10, 20, 30 mmol/L for 10 min respectively. Results: Compared with simple simulated ischemic solution, peak Ito, INa and ICa,L current and current density of ischemic solution containing PCr of 5, 10, 20, 30 mmol/L significantly imp..
