RESUMO
The study group consisted of 50 normal children. The determination of Sinus node func- tions included SNRT, CSNRT, SNRTI, SACT, IHR and autonomic nervous system tone. The A-V conduction system function was evaluated by measurement of wenckeback point and 2:1 point of A-V conduction system. Each parameter was determined before and after com- bined autonomic blockade. Before combined blockade, the Wenckeback point and 2:1 point appeared at the HR of 175-220 bpm were 90% of the cases and 98% of the cases respectively, after combined block- ade, they were 98% of the cases and 100% of the cases respectively. It also showed the domi- nant vagus had effect on A-V node.
