[Necrotizing enterocolitis after an isolated event of supraventricular tachycardia. Case report of atypical neonatal presentation].

Supraventricular tachycardia (SVT) is the main tachyarrhythmia in the newborn (NB) that requires urgent resolution. Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency that mainly affects premature infants. Although these conditions are recognized as distinct pathologies, literature reports suggest that episodes of SVT may predispose patients to NEC secondary to disturbances in mesenteric blood flow and a decrease in tissue perfusion. We present here the clinical case of a premature neonate who developed NEC after an isolated SVT event with low cardiac output.
