Summary
Swallowing can trigger fainting (deglutition syncope), a rare but serious condition. This case highlights the link between swallowing, atrial fibrillation, and gastroesophageal reflux.
Area of Science:
- Cardiology
- Gastroenterology
- Neurology
Background:
- Deglutition syncope is a rare, potentially fatal, yet treatable disorder characterized by fainting episodes triggered by swallowing.
- Recurrent syncope necessitates thorough investigation to rule out underlying cardiac or neurological causes.
Observation:
- A 26-year-old woman presented with recurrent fainting episodes directly linked to swallowing.
- Diagnostic evaluations included 24-hour esophageal manometry, pH monitoring, and continuous electrocardiogram (ECG).
Findings:
- Continuous ECG monitoring revealed multiple symptomatic and asymptomatic episodes of paroxysmal atrial fibrillation.
- Esophageal manometry and pH recordings indicated significant gastroesophageal reflux associated with swallowing events.
Implications:
- This case underscores the importance of considering deglutition syncope in patients with unexplained syncope, especially when associated with swallowing.
- Comprehensive esophageal function testing and continuous electrocardiographic monitoring are crucial for diagnosing this rare condition.
