Ventral root mapping of cardiac nerves in the canine using evoked potentials

D. R. Kostreva, E. J. Zuperku, J. F. Cusick and J. P. Kampine

The sympathetic efferent contribution of left ventral roots T2, T3, and T4 to some cardiac nerves was studied using evoked potentials in mongrel dogs anesthetized with sodium pentobarbital. Electrical stimulation of the ventral roots while recording evoked potentials from the sympathetic chain, anterior ansa subclavia, posterior ansa, ventrolateral cervical cardiac nerve, ventromedial cervical cardiac nerve, and the vagosympathetic trunk demonstrated that A-, B-, and C-type fibers exist in these efferent neural pathways. The range of conduction velocities observed was 0.7-104 m/s. T2 contributed the largest number of A-type fibers, and T2 and T3 contributed C-type fibers equally, while T4 had the least number of fibers coursing through the cardiac nerves.
