The disappearance of these members brings party and constituency preferences into better alignment, thus allowing for the repolarization of congressional parties. Changes in myocardial repolarization in patients undergoing balloon valvuloplasty for congenital pulmonary stenosis: evidence for contraction-excitation feedback in humans. In our calculations, we ignored times of repolarization, when charge was being removed from the model cell. The authors concluded that a defective modulation ofventricular repolarization may favor the onset of malignant arrhythmias and result in sudden death. The role of the potassium channels is, roughly speaking, repolarization. The current did not contribute significantly to the generation of spontaneous action potentials, but it may contribute to the repolarization of the membrane potential. The additional time is the time required for sinus node repolarization. Repolarization occurs when inhibition gets weaker due to declining retinal input rate or adaptation of the inhibitory input. Since the calcium changes during action potentials are confined predominantly to the synaptic terminal, this suggests that the potassium channels that produce repolarization are also located in the synaptic terminal. Inhibiting potassium channels, slowing repolarization, results in slowed atrial-ventricular myocyte repolarization.

It increases influx of sodium through these channels and delays repolarization, thus increasing excitability and promoting ventricular dysrhythmias.

Possible explanations include shortening of ventricular refractoriness (i.e. delayed reactivation of sodium channels) and altered sequence of depolarization and hence inhomogeneity of ventricular repolarization.

The agents from this heterogeneous group have an effect on the repolarization, they prolong the duration of the action potential and the refractory period.

After depolarization, the ions are moved back to their original locations, leading to repolarization of the membrane and relaxation(3).

It delays the repolarization of nerve terminals after a discharge, thereby allowing more calcium to accumulate in the nerve terminal.

Potassium channels are responsible for repolarization of the cardiomyocytes therefore increasing the rate at which cells can depolarize and generate contraction.

In particular, ion pumps play no significant role in the repolarization of the membrane after an action potential.

The delayed rectifier potassium ion current is largely responsible for the repolarization of ventricular cardiac myocytes by permitting potassium efflux.
