As a result of low calcium, there may also be high PTH, which may also lead to low serum phosphate.

由于血钙降低，PTH可能会增高也会导致血清磷酸盐降低。

Low calcium levels, which can cause certain excitable cells to be... more excitable, which result in tetany, muscle spasms, and cardiac dysfunction.

钙水平低，会导致某些可兴奋细胞变得更容易兴奋，可导致抽搐、肌肉痉挛和心脏功能障碍等。

Parathyroid hormone is produced by the parathyroid glands in response to low serum calcium, and it increases bone resorption to release calcium into the bloodstream.

顾名思义，甲状旁腺激素在甲状旁腺产生，来应对血清中过低的钙水平，从而增加骨质的吸收来释放更多的钙进入血液。

Common causes of the long QT are inherited genetic long QTs, electrolyte anomalies, such as low potassium, low calcium or low magnesium, ischemia and a long list of medications.

长QT的常见原因是遗传性长QT、电解质异常，如低钾、低钙或低镁、缺血和一系列药物。

Remember that in response to low calcium, the parathyroid glands release parathyroid hormone, but since calcium just gets wasted, it keeps releasing parathyroid hormone - this is called secondary hyperparathyroidism because the primary problem is with the kidneys.

记住，对于血中低钙的情况，甲状旁腺会释放甲状旁腺激素，但由于钙损失掉了，甲状旁腺会持续释放甲状旁腺激素，这被称为继发性甲状旁腺功能亢进，因为是由肾脏受损引起的。
