Effects of dmLSB on cardiac inward current (a). Current in response to the double step depolarizing pulses (inset). Sets of current traces before (left) and after (middle) the application of 10 μM dmLSB. Notice the slowing of the fast inward current in the presence of dmLSB (arrow heads). Right, voltage dependence of peak amplitude of the current evoked by the second step pulses. The I–V relationships before (open circle) and after (closed circle) the dmLSB application were superimposed (n=4; error bars, s.e.m.). (b) Effects of dmLSB on the inward current in the presence of 100 μM TTX. Sets of current traces in response to the depolarization pulses (inset) before and after bath-applying dmLSB (10 μM).
