Atypical presentations of supraventricular arrhythmias constitute a diagnostic challenge which are not frequently reported in literature. Swallowing-induced supraventricular arrhythmia (SI-SVA), which was first described in 1926, is an intriguing presentation of supraventricular tachycardia and occurs during a wet or solid swallow. A 67-year-old man presented to our outpatient clinic complaining from recurrent episodes of sensation of palpitations and short duration pressure on his chest while swallowing since the last 2 weeks. Ambulatory rhythm Holter monitoring was suggestive of atrial fibrillation (AF) or atrial tachycardia attacks during swallowing. In addition, electrocardiography performed during solid food swallowing, showed short duration of AF consistent with the patient's symptoms. The patient was successfully treated with amiodarone. The main cause of SI-SVA is not known. Cross-talk of nerves during the impulse propagation might be the underlying cause of this phenomenon.
