Malignant hyperthermia

Hyperthermia - malignant; Hyperpyrexia - malignant; MH

Malignant hyperthermia (MH) is a disease that causes a fast rise in body temperature and severe muscle contractions when someone with MH gets general anesthesia. MH is passed down through families.

Hyperthermia means high body temperature. This condition is not the same as hyperthermia from medical emergencies such as heat stroke or infection.
