case_images: Electrocardiograms at admission (electrocardiograms showed a heart rate of only 74 beats per minute with sinus rhythm despite a body temperature of 39.1 C, without arrhythmia, no shortening of the PR segment, ST elevation or depression, and conduction block or T wave change).

case_images: T wave changes (Figure 1). Throughout the clinical course, the echocardiogram demonstrated normal left ventricular function and intracardiac structure, without asynergy.
case_images: The time course of heart rate, fever, and treatment in the case (during the first week of hospitalization, persistently high fever with highest temperature >40 C, the HR remained within 70-100 bpm with sinus rhythm. bpm, beats per minute; BT, body temperature; HR, heart rate; DMX, dexamethasone).

case_images: While hospitalization with a high fever sometimes exceeded 40 C, the HR remained between 70 and 100 bpm with a sinus rhythm (Figure 2).
