Fig. 2From: Protective effect of oxymatrine on chronic rat heart failureRecordings of Ica ∙ L and the average current/capacitance (pA/pF) in different groups. The current was obtained in response to a 400-ms depolarizing step to +10 mV after a prepulse to −40 mV for 300 ms inactivated sodium current from a −40 mV holding potentialBack to article page
