| Repeated operations of the esophagus or stomach carry a risk of vagal injury, which may lead to gastroparesis. |
| In contrast to the innervation of the proximal esophagus, axons from vagal neurons synapse within ganglia of the myenteric plexus. |
| Apparently, the increase in ectopic beats might be related to the increase in vagal tone. |
| Increases in arterial flow stimulate efferent vagal outflow, inhibiting sympathetic drive and decreasing blood pressure. |
| An increase of vagal tone after exercise occasionally can lead to episodes of atrial fibrillation. |
| The increase in high-frequency cardiac modulation is representative of an increase in vagal tone. |
