We read with great interest the case report of swallowing-induced atrial tachycardia (AT) by Higuchi et al. The arrhythmia was refractory to pharmacologic treatment; however, the drugs used were not specified. Subsequently, an electrophysiological study was performed and the swallowing-induced focal trigger was localized in the superior vena cava and was successfully ablated.We would like to share our case of a 71-year-old man with 1-month history of swallowing-induced syncope. Short bursts of presyncope inducing AT during swallowing were recorded at lunch time. We found no pathology on echocardiography, stress testing, or upper gastrointestinalbarium swallow study. Drug treatment with beta blockers was ineffective. Because the mechanism of swallowing-induced syncope was presumed to be vagally mediated, we attempted treating the patient with disopyramide owing to its vagolytic properties, as was already decribed in the literature [2]. After 2 days of therapy with slow-release disopyramide 250 mg twice a day, the patient reported complete abolition of symptoms. To confirm the causal effect, the drug was discontinued and the symptoms recurred almost immediately. Three months after hospital discharge we contacted the patient and found out that he stopped taking the medication and did not experience any palpitations or syncope. We confirmed the complete absence of AT with 72-hour Holter monitoring.Several case reports in the literature address effective pharmacologic therapy of swallowing-induced arrhythmias with remissions lasting even after its termination.2, 3, 4 Therefore, we would like to stress that in similar cases treatment should be principally focused on antiarrhythmic drugs with known vagolytic action, since spontaneous remissions are possible and catheter ablation is an invasive procedure with few, but potentially serious, complications.
