The development of H2O2-induced changes in membrane potentials, membrane currents and corresponding contractile activity (shortening) were studied in rat and guinea-pig ventricular myocytes using the suction-pipette whole-cell clamp method. The cells exhibited a different sensitivity to 30 microM H2O2 in terms of time development of the changes, which were fully irreversible. The observed changes are described in three phases: (1) prolongation of action potential duration (APD) accompanied by… CONTINUE READING
