New onset syncopal events following vagus nerve stimulator implantation might be key to preventing vagus nerve stimulation-induced symptomatic bradycardia — A case report and review

Purpose To identify risk factors for VNS-associated arrhythmia. Methods A literature review identified 14 papers with 21 patients. We compared patients with VNS associated arrhythmia (arrhythmia group, n = 22) and patients without VNS associated arrhythmia (control group of our VNS implanted patients, n = 29). Results New onset syncopal events following VNS placement were seen in the arrhythmia group (p
Highlights • VNS induced bradycardia was misdiagnosed as new onset epileptic seizure. • Post-VNS new onset syncopal events should be monitored carefully. • Cardiac pacemaker treatment resolved bradycardia.
