“…Patients may present with overt syncope or more subtle pre-syncopal symptoms, such as dizziness, lightheadedness, or weakness. 1 Dysphagia and odynophagia have been previously described as presenting symptoms. 1 , 3 , 4 Given its rarity, the overall prevalence of DS cannot be accurately estimated.…”

Deglutition syncope (DS) is a rare, neurally-mediated syncopal syndrome arising from an aberrant vagotonic reflex during swallow-associated esophageal dilation. Its association with gastroesophageal disorders often prompts gastroenterology consultation. An 89-year-old man with recent dysphagia and otalgia was admitted after a syncopal episode occurred while eating. Esophageal imaging and endoscopy demonstrated no causative abnormalities. Maxillofacial imaging revealed chronic sinusitis and mastoiditis. Telemetry monitoring demonstrated high-grade atrioventricular block and pause associated with swallowing. His symptoms and swallow-associated arrhythmia resolved after dual chamber pacemaker implantation. DS is highly treatable once identified and multidisciplinary coordination is helpful in optimizing outcomes and avoiding superfluous testing.

“…Syncope is thought to occur via an aberrant vagal reflex in which esophageal vagal afferents are stimulated by dilation during deglutition, leading to cerebral hypoperfusion via cardiac arrhythmia and/or vasodepression. 1 This condition was first reported by Thomas Spens in 1793. 2…”

“…In cats, indeed, the right and left vagal nerves run along the outer muscle layer of the oesophagus and divide into dorsal and ventral branches just past the heart base 10. In human, oesophageal lesions can also affect cardiac rhythm through a neural reflex mediated by the vagus nerve 11. The so‐called swallow‐syncope is a well‐known phenomenon that can be associated with oesophageal reflux, stenosis or tumours, in which most patients experience bradycardia including sinus or junctional bradycardia and various degrees of atrio‐ventricular blocks.…”

Primary oesophageal squamous cell carcinoma in a cat with bradycardia and ionised hypercalcaemia

An adult male domestic shorthair cat was presented for vomiting and anorexia, with a three-month history of weight loss. Bradycardia was documented during physical examination and was diagnosed as sinusal by electrocardiography. Blood electrolytes analysis revealed a marked ionised hypercalcaemia. Thoracic radiographs revealed a large soft tissue opacity at the level of the distal oesophagus. Subsequent thoracic ultrasonography and oesophagoscopy confirmed the presence of a tissue mass infiltrating distal oesophagus, oesophagogastric junction and neighbouring tissues. After biopsy and histopathological analysis, a squamous cell carcinoma (SCC) was diagnosed. Sinus bradycardia was assumed to be related to an increased vagal tone due to the close proximity of the vagal nerve with the infiltrative lesion or, less likely, severe hypercalcaemia. This case describes an atypical clinical presentation of an SCC in an uncommon location. Furthermore, to the authors’ knowledge, this is the first report of hypercalcaemia associated with oesophageal SCC in a cat.

“…The mechanism has not been fully explained, nor understood. However, it is thought to be due to aberrant vagal stimulation [ 1 ]. This condition occurs most commonly in males, but its prevalence cannot be estimated [ 2 ].…”

Post Total Thyroidectomy Deglutition Syncope

Deglutition syncope is a form of situational syncope where patients develop presyncope or syncope during swallowing. This condition has been observed to occur most commonly in patients with prior gastroesophageal conditions. Our patient developed deglutition syncope that started to occur a few weeks after undergoing a total thyroidectomy. The patient was found to have paroxysmal atrioventricular (AV) block, with up to 5.1 seconds of asystole during swallowing, manifested with episodes of dizziness and lightheadedness. A barium swallow test revealed normal peristalsis and no evidence of dysmotility. The patient underwent placement of a dual chamber pacemaker, and the syncopal episodes resolved. Interrogation of the pacemaker showed no recorded abnormal events.
