| 21. | Repolarization of the membrane potential continues, resulting in an undershoot phase or absolute refractory period.
|
| 22. | The repolarization lasts approximately 75 ms.
|
| 23. | The toxin could increase the duration of the repolarization up to sixfold at 100 �mol / l.
|
| 24. | An increase in entropy during depolarization would release heat; entropy increase during repolarization would absorb heat.
|
| 25. | Under IKr blockade a pronounced INalate can contribute to the development of arrhythmias by increasing repolarization variability.
|
| 26. | During repolarization, the sodium channels begin to become inactivated, causing a net efflux of potassium ions.
|
| 27. | Similarly, the currents that caused repolarization of the active nerve caused slight depolarization in the resting fiber.
|
| 28. | It increases influx of sodium through these channels and delays repolarization, thus increasing excitability and promoting ventricular dysrhythmias.
|
| 29. | In particular, ion pumps play no significant role in the repolarization of the membrane after an action potential.
|
| 30. | Polymorphic ventricular tachycardia, on the other hand, is most commonly caused by abnormalities of ventricular muscle repolarization.
