Radiofrequency ablation of swallowing-induced atrial tachycardia: Case report and review of literature

Swallowing‐Induced Atrial Tachyarrhythmias: Prevalence, Characteristics, and the Results of the Radiofrequency Catheter Ablation

“…Because numerous trials of drugs including the ones affecting the sympathetic or parasympathetic tone effects on the arrhythmia resulted in variable success, with no consistent pattern, their management might be frequently disappointing (Table I). 19,28,34 …”

“…In all five cases, the PACs had the same P‐wave morphology as the first beat of the AT or AF. As mentioned above, an ectopic focus modulated by the autonomic tone appears to be the most likely mechanism, and the treatment of this condition is difficult 19,28,34,35 . Therefore, the RFCA of the ectopic focus should be considered in appropriately selected patients with reliable inducibility and with one or only a few arrhythmia foci.…”

Swallow-induced syncope: A case report of atrial tachycardia originating from the SVC

“…Swallow-induced tachyarrhythmia is rare, and cases described in the literature have reported arrhythmia originating from the atria and pulmonary vein 1 . This is the first report, to our knowledge, of deglutition-induced AT from the SVC.…”

Non‐Contact Three‐Dimensional Mapping and Ablation of Swallowing‐Induced Atrial Tachyarrhythmias: Two Case Reports

“…Therefore, we could not identify the precise mechanism in each case. However, as the previous reports suggested, 1–3 a complex interplay between the sympathetic and parasympathetic nervous systems during swallowing may explain the wide variability in the responses to the autonomic modulation with pharmacologic agents 1–3 …”

“…Mechanical stimulation of the LA by the distended esophagus or a neural reflex (vasovagal reflexes or an adrenergic reflex) are considered to be potential mechanisms of swallowing‐induced tachycardias 1–3 . In a previous study, 7 two cases of PV tachycardias triggered by coughing (1) or talking (1) were reported.…”
