Recurrent atrial fibrillation with nausea and vomiting.
Atrial fibrillation occurred twice during episodes of severe nausea and vomiting in a previously healthy 40-year-old male with new onset of Meniere's syndrome (tinnitus, vertigo, deafness). No organic cause was identified to explain the arrhythmia. Holter monitoring, maximal treadmill stress testing, and sinus node recovery times were normal. Intense vagal stimulation, subsequent bradycardia, and dispersion of atrial tissue refractory period is the likely explanation for this arrhythmia.
