Malignant hyperthermia (MH) is a pharmacogenetic disorder of skeletal muscle most often associated with the administration of volatile general anesthetic agents and/or the muscle relaxant succinylcholine. MH is likely to be fatal if untreated. In most cases, MH is caused by a defect in the ryanodine receptor.
