[Determination of differentially amplified ECG indices for the ventricular complex in healthy children and in children with heart and rheumatic diseases].
As many as fifty healthy children and juveniles who ranged between one to 18 years old were examined together with 25 children presenting with preexcitation syndromes (WPW-syndrome). Registered in all patients was the DAECG tracing. As a result of the studies made it has been found out that indices for the DAECG ventricular complex are age-dependent. DAECG indices characterizing WPW-syndrome are defined.
