Under normal conditions in man, sympathetic activity in muscle nerves occurs in bursts that are synchronized with the cardiac rhythm by inhibitory influence from high-pressure baroreceptors. Analysis of sympathetic outflow following ectopic heart beats indicated that in this situation the activity subsides without being inhibited by a baroreceptor input. It is concluded that the activity has an inherent characteristic of occurring not as a continuous outflow, but in clearly defined bursts.
在人体正常情况下，肌肉神经中的交感神经活动以阵发性形式出现，通过高压压力感受器的抑制作用与心脏节律同步。对异位心跳后交感神经输出的分析表明，在这种情况下，交感神经活动会减弱，而不受压力感受器输入的抑制。由此得出结论，交感神经活动具有一种内在特征，即不是以持续输出的形式出现，而是以明确界定的阵发性形式出现。
