Answer

Acute hypocalcemia may lead to syncopechronic heart failure (CHF), and angina due to the multiple cardiovascular effects. [36] Neuromuscular and neurologic symptoms may also occur. [37]  Neuromuscular symptoms include the following [38] :

  • Numbness and tingling sensations in the perioral area or in the fingers and toes
  • Muscle cramps, particularly in the back and lower extremities; may progress to carpopedal spasm (ie, tetany)
  • Wheezing; may develop from bronchospasm
  • Dysphagia
  • Voice changes (due to laryngospasm)
