Torsades de pointes (TdP) is a rare but hazardous ventricular dysrhythmia caused by an increase in the QT interval of the heart rhythm and is categorized into congenital or acquired types. Signs and symptoms of TdP include syncope, seizure, ventricular fibrillation, and even sudden death. According to statistics, among these symptoms, syncope and the seizure can be considered as signs that make the TdP diagnosis difficult. Here, we present an infant referring to Vali-e-Asr Hospital in Birjand with frequent seizures and aspiration pneumonia. She was diagnosed with Torsades de Pointes and a medium-sized patent ductus arteriosus, and subsequently underwent a patent ductus arteriosus ligation.
