Key result
Eating smaller food portions resolves swallowing-induced palpitations in deglutition-induced atrial tachycardia.
Why the study?
Deglutition-induced atrial tachycardia is a very rare arrhythmia with unclear mechanisms and challenging management.

May reduce symptoms via simple dietary change in deglutition-induced atrial tachycardia; leaves open need for prospective validation.
While bradyarrhythmia is the most common arrhythmia during deglutition, tachycardias are considered to be a very rare condition with approximately 50 cases documented worldwide. The subjects are usually men with no structural heart disease or gastrointestinal pathology, and symptoms may vary from palpitations to lightheadedness or syncope. Management is based on adapting alimentary habits in combination with agents such as beta-blockers, calcium channel blockers, and class IA, IC, and III drugs. Radiofrequency catheter ablation offers a permanent cure in the majority of the reported cases. We report the case of a 51-year-old male with swallowing-induced palpitations, corresponding to brief episodes of atrial tachycardia. Beta-blockers and calcium channel blockers were interrupted because of intolerance. Lifestyle measures with fractionated meals allowing small boluses significantly reduced symptoms. The patient was reticent to invasive measures.

Farah et al. (2021) conducted a case report in Deglutition-induced atrial tachycardia (n=1). Lifestyle measures (fractionated meals with small boluses) was evaluated on Symptom reduction. Lifestyle measures consisting of eating small food portions significantly reduced swallowing-induced palpitations in a patient with deglutition-induced atrial tachycardia.
