    Abstract:
    Sheehan's syndrome, also called Simmond's syndrome, postpartum apoplexy, postpartum pituitary necrosis, and postpartum panhypopituitary syndrome, is the name given to postpartum hypopituitarism. The syndrome is caused by an infarction in the adenohypophysis, usually precipitated by massive uterine haemorrhage and hypovolemic shock during or after childbirth. Extensive destruction of pituitary cells results in varying degree of hypopituitarism. Acute loss of adenohypophysis function can be fatal without glucocorticoid and thyroid replacement therapy and survivors will require life time hormonal replacement therapy. Most cases present in the postpartum period with lactation failure or after months to years after the delivery. In many affected women, anterior pituitary dysfunction is not diagnosed for many years. Dyselectrolytemia is one of a common presentation in Sheehan's syndrome. Herein, we report a case of a 35-year old female with a history of obstetric hysterectomy 2 years ago in view of severe postpartum haemorrhage with history of failure of lactation and three episodes of syncope since last 1½ years and now presented with polymorphic ventricular tachycardia which required DC cardioversion. She was referred as a case of long QT syndrome. On investigating further, she had hypokalaemia secondary to hypopituitarism due to Sheehan's syndrome.
