Abstract
In acute experiments, synchronization of cardiac and vagal rhythms was achieved during burst stimulation of a vagus nerve. The study of atrial excitability in the synchronization revealed changes of diastolic threshold, effective and total refractory periods, the changes being unrelated to the synchronization phenomenon and due to variation of the heart rate.
摘要
在急性实验中，迷走神经爆发性刺激期间实现了心脏节律与迷走神经节律的同步。对同步过程中的心房兴奋性研究揭示了舒张期阈值、有效不应期和总不应期的变化，这些变化与同步现象无关，而是由心率变化所致。
