T-Wave Alternans in Nonpathological Preterm Infants.
Marcantoni I, Sbrollini A, Agostinelli G, Surace FC, Colaneri M, Morettini M, Pozzi M, Burattini L. Marcantoni I, et al. Ann Noninvasive Electrocardiol. 2020 Jul;25(4):e12745. doi: 10.1111/anec.12745. Epub 2020 Jan 27. Ann Noninvasive Electrocardiol. 2020. PMID: 31986237 Free PMC article.
BACKGROUND: Sudden infant death syndrome is more frequent in preterm infants (PTI) than term infants and may be due to cardiac repolarization instability, which may manifest as T-wave alternans (TWA) on the electrocardiogram (ECG). Therefore, the aim of the p …
