We studied phrenic nerve conduction times in 90 phrenic nerves of 45 normal subjects. The phrenic nerve was stimulated at the posterior border of the sternomastoid muscle in the supraclavicular fossa, just above the clavicle, with bipolar surface electrodes. For recording, positive and negative electrodes were placed on the xiphoid process and at the eighth intercostal bone-cartilage transition, respectively. We studied both the right and left sides to determine whether there was any difference between the two sides. The mean onset latency (± SD) of the right compound muscle action potentials (CMAPs) (5.99±0.39 msec) was significantly shorter than that of the left CMAPs (6.45±0.50 msec). The mean peak latency was significantly shorter in the right CMAPs (10.22±1.33 msec) than the left CMAPs (12.48±2.02 msec). The mean (± SD) amplitude was significantly lower in the left CMAPs (0.42±0.11 mV) than the right CMAPs (0.49±0.10 mV). The difference between the length of the nerve on the right and left sides might have affected the difference in latency between the two sides.
