In this report, the influence of the autonomic nervous system on the accessory pathway (Kent and Mahaim fibers) is discussed, based on electrophysiological and centrifuge examination results in two military pilots. We demonstrated that catecholamines reduce the effective refractory period (ERP) and improve conductivity in both the atrio-ventricular node (A-V node) and the accessory pathway. We concluded that the pattern of intermittent preexcitation may be connected with phenomenon of the 3rd and 4th phase block of the functional potential in the accessory pathway, and that in some cases the +Gz gravitoinertial tolerance test performed on the human centrifuge may help in distinguishing subjects with the intermittent preexcitation syndrome. Finally we concluded that all pilots with preexcitation syndrome should be dismissed from flying.
在本报告中，基于对两名军事飞行员的电生理和离心机检查结果，讨论了自主神经系统对旁路（肯特纤维和马海姆纤维）的影响。我们证明，儿茶酚胺可缩短房室结和旁路的有效不应期（ERP）并改善传导性。我们得出结论，间歇性预激模式可能与旁路功能电位的第三和第四期阻滞现象有关，并且在某些情况下，在人体离心机上进行的+Gz重力惯性耐力试验可能有助于区分患有间歇性预激综合征的受试者。最后我们得出结论，所有患有预激综合征的飞行员都应停飞。
