What does malignant hyperthermia cause? -- Answer ✔✔ High intracellular calcium
causes uncontrollable muscle contractions and hypermetabolism, i.e. high temperature,
metabolic acidosis and muscle rigidity
What is it caused by? -- Answer ✔✔ Genetic defect in sarcoplasmic reticulum channels,
causing it to open more easily and close slower.
