Summary An electrocardiographic study was performed on 56 healthy children during their first week of life. Recordings were made repeatedly on every child using a long recording time. Leads I, II, III, aVR, aVL, aVF, VI, V2, V3, V4, V5, V6 were recorded. Extreme fluctuations of the heart rate, a high frequency of sinus arrhythmia and supraventricular arrhythmia, signs of right ventricular hypertrophy, extremely low T waves with significant T wave changes during the first week and in some cases prolonged Q‐T intervals were observed. My thanks are due to Å. Gyllensward, M. D., for advice and criticism.
