This investigation was undertaken to differentiate the vagal effects between right and left vagus on heart rate and blood pressure in rabbit. Electrical stimulation was applied on the vagi in cervical region to peripheral and cranial end before or after cutting the vagi. The heart rate and blood pressure change were recorded and analized.
The results may be summarized as follows:
1. Right vagal efferent fiber stimulation inhibited the cardiac function more significantly than the left.
2. In the vagal afferent fiber stimulation, there were no difference between the right and left on blood pressure and heart rate.
In the above results, right vagal efferent fiber to the heart may be dominant than left vagus in rabbit.
