General Discussion

Malignant Hyperthermia (MH) is a pharmacogenetic channelopathy affecting skeletal muscle. When MH-susceptible individual are given potent inhalational agents (halothane, sevoflurane, desflurane, etc.) and/or succinylcholine, they can develop a hypermetabolic state that can rapidly progress to a high temperature, muscle rigidity, cardiac arrest, and ultimately may lead to death.
