Abstract
Vagus nerve stimulation (VNS) therapy is approved in the United States by the FDA in 1997 for medically refractory partial epilepsy in patients of ages 12 years and above. The most common stimulation-associated side effects are voice alteration, hoarseness, throat and neck pain, headache, cough, and dyspnea. Four patients with VNS had late-onset bradycardia and asystole, attributed to VNS stimulation. Their ages were 13, 17, 47, and 55. Cardiac symptoms were noted after 2.33–9 years postimplantation [1–4]. Three cases had symptoms correlated with stimulation, monitored by electrocardiogram [1,2,4]. This new case report highlights cardiac syncope with very similar clinical presentation as previous four cases, and raises the concern for cardiac symptoms, even many years after VNS implantation.
