In intact rats vagal stimulation reduced heart rate, but had no effect on stroke volume. In sympathectomized animals this treatment decreased both the heart rate and stroke volume. Sympathectomized rats displayed higher sensitivity to vagal nerve stimulation compared to intact animals of the same age (except for rats aging 21 and 56 days).
在完整大鼠中,迷走神经刺激可降低心率,但对每搏输出量无影响。在去交感神经的动物中,这种处理可降低心率和每搏输出量。与同龄的完整动物相比(21日龄和56日龄的大鼠除外),去交感神经的大鼠对迷走神经刺激表现出更高的敏感性。
