As a result, the muscle cannot contract efficiently (paralysis). The condition is hypokalemic (manifests when potassium is low; not "causing hypokalemia") because a low extracellular potassium ion concentration will cause the muscle to repolarise to the resting potential more quickly, so even if calcium conductance does occur it cannot be ...
