Primary cardiac tumors in the fetal and neonatal populations are rare. In neonates, these tumors may present with a range of clinical manifestations, from asymptomatic cases to severe arrhythmias, valvular obstruction, and cardiac dysfunction. This report describes a case of fatal malignant arrhythmia caused by a cardiac tumor in an 8-day-old neonate. The electrocardiogram at birth revealed multiple abnormalities, including ST-T segment alterations, intraventricular conduction block, and bundle branch block. By the sixth postnatal day, the patient 2 developed rapid, polymorphic malignant ventricular arrhythmias. Despite aggressive treatment, the neonate ultimately suffered sudden cardiac death. This case underscores the potentially fatal risk of arrhythmias associated with cardiac tumors.
