| Type | MGI:General | Description | prolonged action potential duration at frequencies less than 4 Hz and smaller dV/dt(max) at all frequencies tested ventricular myocytes show reduced peak sodium current densities and prolonged current decay half-life (at voltages from -45 to -25 mV) at room temperature upstroke velocity (dV/dt(max)) of the elicited action potential is reduced by 31% at -120 mV the current density of persistent sodium currents is significantly larger at voltages between -90 and -10 mV |
