(12,14,24,25) The QT interval represents the total time needed for the ventricles to depolarize and
repolarize. The QT interval's duration in our study (0.12 seconds) approximated that reported previously in partridges (A graeca and A chukar).
When the balloons parted ways, they would
repolarize in the electrical field around them.
The increased conductance for [K.sup.+] will
repolarize the membrane back to its resting level.
Under normal conditions, neurons have a period of rest that allows membranes to
repolarize. However, chronic electric simulation affects the depletion of neurotransmitters, consequently impeding neuronal activation [49].
This antagonism could be important to allow the neuron to correctly
repolarize its microtubules before growing the new axon, the researchers said.
QT prolongation is indicated by an increase in the decay/rise ratio, as this reflects a delay in the ability to
repolarize the action potential and start another beat.
The sinoatrial nodule generates electrical signals, which depolarize and
repolarize the synaptic membranes, which leads to rhythmicity of the heart (2), also known as heart rate variability (HRV) (3).
During phase 3 of the AP, the L-type Ca [sup]2+ channels close, while the slow delayed rectifier K [sup]+ channels are still open, allowing more K [sup]+ channels to open, causing the cell to
repolarize. The third phase of repolarization terminates the AP and returns the membrane potential to phase 4.
These calcium channels influence the voltage-dependent potassium channels to
repolarize the cell membrane, leading to closure of the voltage-dependent calcium channels.
