Abstract: | Muscle biopsy and in vitro contracture tests for diagnosis ofsusceptibility to malignant hyperthermia (MH) were performedin two patients who had developed fever and severe myolysisduring exercise. MH susceptibility was confirmed in one patientbut in the other, exercise-induced heat stroke proved to bethe correct diagnosis. Clinical presentation and epidemiologyof exercise-induced MH and its relation to the heat stroke syndromeare discussed. |
