the repolarisation phase of the cardiac action potential. Variants in KCNQ1 that decrease IKs (loss of function variants) slow the repolarisation of the...

junction of the cardiac nerves[citation needed]. This shortens the repolarisation period, thus speeding the rate of depolarisation and contraction, which...

inactivation. Phase 1: Rapid repolarisation. Phase 2: Plateau, the longest phase, approximately 100ms. Phase 3: Rapid repolarisation, which returns the membrane...

QT prolongation is a measure of delayed ventricular repolarisation, which means the heart muscle takes longer than normal to recharge between beats. It...

Andersen–Tawil decreases the flow of potassium, slowing the rate of repolarisation which can be seen in individual cardiac muscle cells as a longer action...

variations are linked with Long QT syndrome, a disorder that affects repolarisation (relaxing) of the heart after a heartbeat, giving rise to an abnormally...

The potassium channels exhibit a delayed reaction to the membrane repolarisation, and, even after the resting potential is achieved, some potassium continues...
