Key result
Permanent pacemaker implantation successfully resolved recurrent syncopal attacks in a 66-year-old woman with swallow-induced atrial and ventricular asystoles.
Case Report (n=1)
Permanent pacemaker implantation can effectively resolve symptoms in patients with swallow syncope caused by swallowing-induced asystole.
May inform pacing decisions in rare swallow syncope; leaves open need for confirmatory studies before practice change.
Swallow syncope is a relatively rare syndrome that is treatable when diagnosed. A 66-year-old woman was referred to the department of cardiology because she had been suffering from recurrent syncopal attacks associated with swallowing. An ambulatory electrocardiogram revealed atrial and ventricular asystoles immediately after swallowing soup or tea that were reproducible (max. RR 3.5 s). An electrophysiological study did not detect sinus nodal or atrioventricular nodal dysfunction. The patient had no underlying esophageal disease or cardiac disorder. The patient's symptoms resolved after permanent pacemaker implantation. This report reviews the diagnosis, mechanism and management of swallow syncope.
