| vagal | <anatomy> Pertaining to the vagus nerve. (18 Nov 1997) |
|---|---|
| vagal attack | <syndrome> Syndrome consisting of palpitation, chest pain, respiratory difficulties, and disturbances in gastric motility; once attributed to vagal stimulation, now considered psychogenic (anxiety neurosis). Synonym: vagal attack, vasovagal attack. (05 Mar 2000) |
| vagal bradycardia | Any excessive cardiac slowing due to stimulation of the vagus nerves. (05 Mar 2000) |
| vagal part | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| vagal part of accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| vagal trigone | A prominence in the floor of the inferior fovea of the fourth ventricle that overlies the dorsal motor nucleus of the vagus. Synonym: trigonum nervi vagi, ala cinerea, ashen wing, gray wing, trigone of vagus nerve, va'gi eminentia. (05 Mar 2000) |
| vagal trunk | One of the two nerve bundles, anterior and posterior, into which the oesophageal plexus continues as it passes through the diaphragm. Synonym: truncus vagalis. (05 Mar 2000) |
| gastric branches of anterior vagal trunk | Anterior gastric branches of the vagus; branches of the anterior vagal trunk to the anterior surface of the stomach. Synonym: rami gastrici anteriores nervi vagi. (05 Mar 2000) |
| gastric branches of posterior vagal trunk | Posterior gastric branches; branches of the posterior vagal trunk to the posterior surface of the stomach. Synonym: rami gastrici posteriores nervi vagi. (05 Mar 2000) |
| dorsal vagal nucleus | The visceral motor nucleus located in the vagal trigone (ala cinerea) of the floor of the fourth ventricle. It gives rise to the parasympathetic fibres of the vagus nerve innervating the heart muscle and the smooth musculature and glands of the respiratory and intestinal tracts. Synonym: nucleus dorsalis nervi vagi, dorsal motor nucleus of vagus, dorsal nucleus of vagus, dorsal vagal nucleus, nucleus alae cinereae. (05 Mar 2000) |
| anti-arrhythmia agents | Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibres. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade. (12 Dec 1998) |
| arrhythmia | <cardiology, physiology> Any variation from the normal rhythm of the heart beat, including sinus arrhythmia, premature beat, heart block, atrial fibrillation, atrial flutter, pulsus alternans and paroxysmal tachycardia. Origin: Gr. Rhythmos = rhythm (18 Nov 1997) |
| arrhythmia, sinus | Irregularity of the heart rate related to functioning of the sinoatrial node. (12 Dec 1998) |
| cardiac arrhythmia | A disturbance the electrical activity of the heart that manifests as an abnormality in heart rate or heart rhythm. Patients with a cardiac arrhythmia may experience a wide variety of symptoms ranging from palpitations to fainting. (27 Sep 1997) |
| ventricular arrhythmia | <cardiology> A cardiac arrhythmia which originates from within the ventricles. Isolated ventricular contractions are referred to as premature ventricular contractions. Frequent premature ventricular contractions can be potentially unstable and can degrade to a more serious rhythm or cardiac arrest. (12 Jan 1998) |
