Malignant hyperthermia is disease passed down through families that causes a fast rise in body temperature (fever) and severe muscle contractions when the affected person gets general anesthesia.

This condition is not the same as hyperthermia that is due to medical emergencies such as heat stroke or infection.

Hyperthermia - malignant; Hyperpyrexia - malignant

Malignant hyperthermia is inherited. Only one parent has to carry the disease for a child to inherit the condition.

It may occur with muscle diseases such as multiminicore myopathy and central core disease.
