Deglutition01:25

Deglutition

7.6K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

3.9K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

2.2K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Narcolepsy01:07

Narcolepsy

739
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Esophagus01:24

Esophagus

4.5K
The esophagus, a muscular conduit linking the pharynx and stomach, measures roughly 10 inches (25.4 cm) and sits behind the trachea. It remains collapsed when not swallowing. The esophagus follows a predominantly straight path through the thoracic mediastinum and enters the abdominal cavity through a diaphragmatic opening known as the esophageal hiatus.
The movement of edibles from the pharynx into the esophagus is facilitated by the upper esophageal sphincter, which is formed primarily by the...

Sleep Apnea01:21

Sleep Apnea

753
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Area of Science:

  • Cardiology
  • Pediatric Electrophysiology
  • Syncope Syndromes

Background:

  • Swallowing (deglutition) can precipitate syncope, a transient loss of consciousness, often linked to cardiovascular events.
  • Sinus venosus atrial septal defects (SVASDs) are congenital heart anomalies that may require surgical repair.
  • Transient atrioventricular block can occur post-cardiac surgery, necessitating careful monitoring and management.

Observation:

  • A 13-year-old patient, post-SVASD repair, presented with recurrent episodes of syncope.
  • These syncopal episodes were associated with transient complete atrioventricular block.
  • The patient's symptoms were triggered by swallowing, indicating a potential deglutition syncope mechanism.

Findings:

  • The patient exhibited intermittent complete atrioventricular block, specifically during swallowing events.
  • Diagnostic evaluation confirmed the link between deglutition and cardiac electrical disturbances.
  • The underlying cause was suspected to be related to the surgical repair of the SVASD.

Implications:

  • This case highlights the importance of considering swallowing as a trigger for syncope, particularly in young patients with congenital heart disease history.
  • Prompt recognition and diagnosis of deglutition syncope and associated atrioventricular block are crucial for preventing adverse outcomes.
  • Pacemaker implantation proved an effective therapeutic strategy for managing this rare presentation of swallowing-induced syncope and atrioventricular block.
