Objective monitoring revealed that 15 of 16 children and adolescents with inherited arrhythmia syndromes exceeded the recommended 7 MET activity threshold during routine free-living activities.
Observational (n=16)
Children and adolescents with inherited arrhythmia syndromes frequently exceed the recommended <7 MET activity restriction during routine daily life.
BACKGROUND: International guidelines recommend restriction of activities for many children and adolescents with inherited arrhythmia syndromes to moderate activity (7 MET threshold was 113 (65-330) minutes, whereas such time spent >10 MET threshold was 53 (9-115) minutes. Total time>7 MET threshold was 2.3% of monitor wear time. There were no differences in time above threshold between male and female participants (P=0.357) or among those with different levels of activity restriction (P=0.769). CONCLUSIONS: Current recommended activity guidelines are frequently exceeded during routine free-living activities in young participants with inherited arrhythmia syndromes. Whether this indicates increased risk for these individuals or excessively restrictive guidelines remains to be determined.
Gow et al. (Sat,) conducted a observational in Inherited arrhythmia syndromes (n=16). Combined heart rate and accelerometry monitor (Actiheart) was evaluated on Exceeding vigorous (7 MET) and very vigorous (10 MET) activity thresholds. Objective monitoring revealed that 15 of 16 children and adolescents with inherited arrhythmia syndromes exceeded the recommended 7 MET activity threshold during routine free-living activities.
