recommendations! Published in 2024 at "JAMA cardiology"

DOI: 10.1001/jamacardio.2024.0039

Abstract: Importance Congenital long QT syndrome (LQTS) is associated with syncope, ventricular arrhythmias, and sudden death. Half of patients with LQTS have a normal or borderline-normal QT interval despite LQTS often being detected by QT prolongation… read more here.

DOI: 10.1016/j.ajog.2019.09.004

Abstract: BACKGROUND Most fetal deaths are unexplained. Long QT syndrome (LQTS) is a genetic disorder of cardiac ion channels. Affected individuals, including fetuses, are predisposed to sudden death. We sought to determine the risk of fetal… read more here.

DOI: 10.1016/j.hrthm.2020.08.017

Abstract: BACKGROUND In patients with long QT syndrome (LQTS), swimming and loud noises have been identified as genotype-specific arrhythmic triggers in LQTS type 1 and LQTS type 2, respectively. OBJECTIVE To compare LQTS groups' responses to… read more here.

DOI: 10.1016/j.hrthm.2022.01.041

Abstract: BACKGROUND Long QT syndrome (LQTS) is an autosomal dominant disorder characterized by a prolonged QT interval. ECG screening in the first 48 hours of life may be misleading, even in newborns with a genotype-positive LQTS… read more here.

DOI: 10.1136/bcr-2021-242362

Abstract: Congenital long QT syndrome (LQTS) is a genetically autosomal heterogeneous disorder of the ion channels and causes about 10% of sudden death infant syndrome in newborns. Its estimated prevalence is approximately 1 in 2500, probably… read more here.

DOI: 10.1161/circ.142.suppl_3.14500

Abstract: Introduction: The safety of vigorous exercise for individuals with appropriately-treated LQTS remains unproven, and physical activity practices in this population have not been described. Methods: LIVE-LQTS prospectively enrolled individuals age 8-60 years with overt LQTS… read more here.

DOI: 10.1161/circ.152.suppl_3.4364602

Abstract: Background: Congenital long QT syndrome (LQTS) is characterized by a prolongation of the heart rate-corrected QT interval (QTc) and an increased risk of syncope, seizure and sudden cardiac arrest/death (SCA/SCD). Genome-wide association studies have identified… read more here.

DOI: 10.1161/circulationaha.118.033943

Abstract: Background: Long QT syndrome (LQTS) is associated with potentially fatal arrhythmias. Treatment is very effective, but its diagnosis may be challenging. Importantly, different methods are used to assess the QT interval, which makes its recognition… read more here.

DOI: 10.1161/circulationaha.123.067590

Abstract: BACKGROUND: Whether vigorous exercise increases risk of ventricular arrhythmias for individuals diagnosed and treated for congenital long QT syndrome (LQTS) remains unknown. METHODS: The National Institutes of Health–funded LIVE-LQTS study (Lifestyle and Exercise in the… read more here.
