The experiments were performed on rabbits anaesthetized with urethane and chloralose. The ECG heart rate and blood pressure were recorded. The power spectrum analysis of R-R interval (RRI) was done by computer. Electrical stimulation of nucleus ambiguus (NA), depressor nerve (DN) and the peripheral end of right vagus (RV) all evoked a decrease in heart rate and blood pressure (P < 0.001), and an increase in LF, HF, LF/HF, TV and VLF (P < 0.05-0.001); The LF, HF, LF/HF, TV and VLF were…

TLDR
The results revealed that there is an obvious coherence between the blood pressure and neuronal discharge in the rostral ventrolateral medulla of rats that indicates the integration of cardiac cycle and respiratory rhythm in the RVLM that might be important in cardiorespiratory homeostasis.
