Web- an action potential is an all or none event, if a nerve is at rest the amplitude on one action potential will be the same all along the nerve independent of the stimulus strength. - threshold reflects the need to trigger the opening of the voltage-gated sodium channel (need a depolarization of about 10 to 15 mV to open) WebThe action potential duration is longest in the midmyocardial region. 2 The average duration of the ventricular action potential duration is reflected in the QT interval on the ECG. Factors that prolong the action potential duration (eg, a decrease in outward K + currents or an increase in inward late Na + current) prolong the action potential duration …
