It has repeatedly been shown that EHS can occur in well-trained patients with known MH-associated mutation in the RYR1 gene in the absence of any extreme environmental conditions or extreme physical activity, thereby supporting a possible link between EHS and MH. In this case, a highly trained 30-year-old male athlete suddenly collapsed while running. He had initial hyperthermia (40.2\u00b0C) and progressive multiple organ failure requiring medical management in an intensive care unit. After he recovered completely, a maximal exercise test was performed and showed an obvious abnormality of oxidative metabolism in muscle; genetic analysis of the RYR1 gene identified a heterozygous missense variation p.K1393R. Consequently, the athlete was given appropriate information and allowed to progressively return to sport competition.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Differential Diagnosis<\/jats:title>\n                  <jats:p>\u2003Doping, use of drugs and toxic agents, exercise-associated hyponatremia, exertional heat illness.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Treatment<\/jats:title>\n                  <jats:p>\u2003Initial management started with the basic resuscitative guidelines of airway, breathing, and circulation (intubation).
