CRITERIONS OF EVALUATION OF CARDIAC ACTIVITY DAMAGE ADAPTATION IN CHILDREN WITH CONGENITAL HEART DISEASE
We determined CPK-MB activity, the index of cardiac rhythm variability in 30 children with congenital heart disease - open arterial canal after cardiosurgical correction together with clinical examination. 3 months after cardiosurgical operation we registered an increased CPK-MB activity in blood serum and a decrease in coefficient K of heart rate variability 30/15 in the period of cardiac activity adaptation. A change of these indexes correlates with high reliability, which indicates impaired cardiac activity. The studied tests can serve as additional indications of cardiac activity evaluation of cardiac activity adaptation of children after surgery for cardiac failure.
