Swallowing induced atrial tachycardia and fibrillation in a patient with a Wolf-Parkinson-White syndrome

A 56-year-old man with the Wolf-Parkinson-White (WPW) syndrome (type A) is described. His presenting signs were paroxysmal atrial tachycardia and fibrillation induced by swallowing. This supraventricular tachyarrhythmia (SVT) could be abolished by performing the valsalva maneuver or carotid stimulation, and prevented only by treatment with amiodarone.
