Study: NCT05322772

Intervention type: DEVICE
Intervention: ECG
Description: ii. 12 leads ECG: 12 leads ECG will be done to all infants \& children using (FUKUDA DENSHI, CARDIMAX, model FCP 7101). The electrocardiograms will be reviewed through the creation of descriptive reports and determination of the following variables: heart rate, QRS duration, The QT interval was measured from the onset of the QRS complex to the end of the T wave, defined by the return of the terminal T wave to the isoelectric T-P baseline. When U waves were present, the end of the T wave will be taken as the nadir between the T and U waves. Then QT interval will be corrected for heart rate using Bazett's formula Interpretation of every ECG paper
