Effort hyperthermia

Heat bufe due to physical exercise and its continuation in the malignant effort

hyperthermia are clinical units characterized by the inefficiency of thermoregulation

mechanisms. This pathology seldom met, that underlies an insuffiency: polivisceral, must

be known, because the initial treatment influences the prognosis.
