Electrocardiography was performed before the episode. No ST segment elevation was observed in the right precordial leads.

During his hospitalization in the Department of Psychiatry, the patient had undergone electrocardiography at least once a month, and no Brugada-type waveforms had been seen (Fig. 1).
A Brugada-type electrocardiographic pattern can be seen in the right precordial leads.

On the electrocardiogram that was obtained after the diagnosis of pneumonia, however, coved-type ST segment elevation was observed in leads V1-3 (Fig. 2).
The serial changes in the electrocardiographic findings, body temperature, the blood concentrations of carbamazepine and valproic acid, the thyroid function and the serum potassium levels are shown. The coved-type ST segment elevation improved in proportion to the decrease in the level of carbamazepine.

Furthermore, the patient's body temperature (whether the patient was febrile or not) was not associated with the electrocardiographic changes (Fig. 3).
