ECG immediately after defibrillation showed sinus tachycardia with a prolonged QT interval and a giant T-wave inversion in leads V1-V6, I and AVL.

T-wave inversion in leads I, AVL and V1-V6 (Figure 1). The patient's further course of illness was turbulent, and recurrent episodes of haemodynamically unstable ventricular tachycardia required cardioversion (Figure 2).
ECG after 2 h showed ventricular tachycardia.

T-wave inversion in leads I, AVL and V1-V6 (Figure 1). The patient's further course of illness was turbulent, and recurrent episodes of haemodynamically unstable ventricular tachycardia required cardioversion (Figure 2).
ECG after 2.5 h showed marked ST-segment elevation in leads V1-V6, I and AVL.

Subsequent ECG showed transient ST-segment elevation in leads I, AVL and V1-V6 (Figure 3).
Pituitary MRI and the red arrow show that the pituitary gland was replaced by cerebrospinal fluid.

Pituitary magnetic resonance imaging (MRI) showed that the pituitary gland had almost disappeared and was filled with cerebrospinal fluid (Figure 4).
ECG after 1 month showed that corrected QT interval had returned to normal.

The patient did not take antiarrhythmic drugs, and with hormone replacement therapy, her condition gradually stabilized, the ejection fraction (EF) increased from 45% to 55%, and the corrected QTc returned to normal (Figure 5).
