Malignant hyperthermia (MH) is a potentially fatal pharmacogenetic disease
triggered by several anaesthetic agents. The in vitro muscle contracture te
st (IVCT) is the standard test to establish an individual's risk of suscept
ibility to MH. Clinical practitioners and geneticists of the European MH Gr
oup have agreed on the present guidelines for the detection of MH susceptib
ility using molecular genetic techniques and/or IVCT to predict the risk of
MH.
