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).

T wave changes (Figure 1). Throughout the clinical course, the echocardiogram demonstrated normal left ventricular function and intracardiac structure, without asynergy.
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).

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