Hypocalcaemia leading to supra ventricular tachycardia in a three-month old Sri Lankan infant with vitamin D deficient rickets: a case report

Supra ventricular tachycardia is is known to occur in infancy. However, only a single publication reports supra ventricular tachycardia occurring due to hypocalcaemia [1]. Hypocalcaemia during infancy can be due to many reasons. Vitamin D deficient rickets is one of them [2, 3]. There are only a few reports regarding symptomatic hypocalcaemia due to nutritional rickets. We could not find any reports of association between supra ventricular tachycardia and vitamin D deficient rickets.
