Physical Activity in Paediatric Long QT Syndrome Patients

BackgroundPhysical activity (PA) is important for cardiovascular health as well social and emotional well-being of children. Patients with long QT syndrome (LQTS) often face PA restrictions are prescribed beta-blockers disease management. The aim this study was to determine if levels were lower in patients LQTS compared healthy controls.MethodsParticipants from an inherited arrhythmia clinic completed the Physical Activity Questionnaire Children Adolescents (PAQ-C/A) exercise stress test. PAQ score (a general measure youth, unitless) endurance time controls.ResultsTwenty-three had test within a year having PAQ. No difference observed scores between control groups (LQTS: 2.3 ± 0.15 vs controls: 0.18; P = 0.78). There no effect age on (P > 0.05), whereas significantly decreased controls (eg, 11-12 17-20 years: 3.2 0.07 1.5 0.08, 0.005). Endurance heart rate at peak (11 0.5 15 minutes, < 0.0001; 169 5 198 2 beats per minute, 0.0001).ConclusionsDespite guideline recommendations restricting PA, risk sudden cardiac death, use beta-blockers, our cohort reported similar controls.
