Promising news from Erasmus MC Sophia Children’s Hospital: new data show that wrist-worn wearables offer a more comfortable alternative for heart rate monitoring in children with congenital heart disease or arrhythmias. The study found that Corsano CardioWatch measures heart rate well during and are much more pleasant to wear than traditional Holter ECG recorders. This is an important benefit for children who often need repeated monitoring. “Wearables measure the heart rate of children with congenital heart disease or arrhythmias well and are more comfortable to wear than a Holter ECG” said Hidde Hardon, Researcher, Erasmus MC Sophia Children’s Hospital Study highlights of The Validation and Accuracy of Wearable Heart Rate Trackers in Children With Heart Disease (Prospective Cohort Study JMIR Formative Research, 2025): 31 participants (mean age 13.2 ± 3.6 years; 45% female) and 36 participants (mean age 13.3 ± 3.9 years) were included for the study. Mean accuracy for CardioWatch was 84.8% ± 8.7%, and 90.9% ± 9.3% at lower heart rates. These results suggest that Corsano CardioWatch wearables can be a valuable addition to pediatric cardiology, making heart rate monitoring more comfortable, simpler and reliable in many use cases.
