Recording an ECG With a Smartwatch in Newborns and Young Children: Feasibility and Perspectives

Published:August 06, 2021DOI:


      Correlating symptoms with arrhythmia in neonates and young children is often difficult because of their sporadic and unpredictable nature. We show that it is possible to register an ECG with a smartwatch in neonates and young children and provide illustrative cases of supraventricular tachycardia and complete atrioventricular block identified with this technology.


      Faire la corrélation entre symptômes et arythmie chez les nouveau-nés et les jeunes enfants est souvent difficile en raison de leur nature sporadique et imprévisible. Nous montrons ici qu'il est possible d'enregistrer un ECG avec une montre connectée chez les nouveau-nés et les jeunes enfants et fournissons des exemples de cas de tachycardie supraventriculaire et de bloc auriculo-ventriculaire complet identifiés grâce à cette technologie.

          Leroux et al. should be congratulated for their recent article in the Canadian Journal of Cardiology,1 showing the feasibility of recording smartwatch electrocardiograms (ECGs) in newborns and young children. They recorded 2 leads in each case: the conventional lead I following the instructions of the smartwatch and a precordial lead (actually a CR lead) using our method,2 placing the back of the watch in the precordium and touching the crown with the child's right-hand finger. In the reported cases, the ECG is of good quality to obtain a diagnosis.
