Ventricular tachycardia in congenital adrenal hyperplasia.

Severe hyperkalaemia in patients with congenital adrenal hyperplasia in association with aggravating factors such as acidosis and hypocalcaemia can cause life-threatening ventricular arrhythmias. Treatment of the underlying cause may be the only modality required in such cases. We report a 20-day-old male presenting with ventricular tachycardia due to electrolyte abnormalities in salt-losing congenital adrenal hyperplasia. Sudden cardiac deaths reported earlier in such cases thus gain credence.
