case_images: 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.

case_images: fig1-2050313X221147194
case_images: 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).
case_images: ECG after 2 h showed ventricular tachycardia.

case_images: fig2-2050313X221147194
case_images: 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).
case_images: ECG after 2.5 h showed marked ST-segment elevation in leads V1-V6, I and AVL.

case_images: fig3-2050313X221147194
case_images: Subsequent ECG showed transient ST-segment elevation in leads I, AVL and V1-V6 (Figure 3).
case_images: Pituitary MRI and the red arrow show that the pituitary gland was replaced by cerebrospinal fluid.

case_images: fig4-2050313X221147194
case_images: Pituitary magnetic resonance imaging (MRI) showed that the pituitary gland had almost disappeared and was filled with cerebrospinal fluid (Figure 4).
case_images: ECG after 1 month showed that corrected QT interval had returned to normal.

case_images: fig5-2050313X221147194
case_images: 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).
