Normal values of M mode echocardiographic measurements of more than 2000 healthy infants and children in central Europe

OBJECTIVE—To obtain normal M mode (one dimensional) echocardiographic values in a substantial sample of normal infants and children.
DESIGN—Data were obtained over three years from a single centre in central Europe.
PATIENTS—2036 healthy infants and children aged one day to 18 years.
METHODS—In line with recommendations for standardising measurements from M mode echocardiograms, and using digital echocardiographic equipment, measurements were obtained of the following: right ventricular anterior wall thickness at end diastole, right ventricular end diastolic dimension, thickness of interventricular septum at end diastole and end systole, thickness of posterior wall of the left ventricle at …
