case_images: The electroencephalogram (ECG) showed sinus tachycardia, with heart rate 137 bpm and QT interval 421 ms (Figure 1).
case_images: Electrocardiography of the patient showing sinus tachycardia about 24 hours after taking clozapine.

case_images: The serum concentrations of clozapine and norclozapine were continuously monitored during hospitalization to evaluate the treatment effect (Figure 3).
case_images: The clozapine levels and the VDI index during hospitalization.

case_images: During drug redistribution however, the clozapine levels recovered and the VDI index increased simultaneously (Table 3 and Figure 4).
case_images: A positive correlation between VDI index and serum concentration of clozapine.

case_images: Thus, there was a positive correlation between VDI index and serum concentration of clozapine (Figure 5).
