The 12-lead ECG (Figure 1, column 2) on admission showed sinus tachycardia, anterior left hemiblock, prolonged QT interval (360 ms), QRS widening (140 ms) and a marked ST tract elevation in leads V1-V6 and aVR. After twelve days her blood levels of amitriptyline were still above the therapeutic range (490 ng/ml; normal values between 100-250 ng/ml) but ECG abnormalities were no longer present (Figure 1, column 1 and column 7).
