Introduction: Herein we report our experience with the repetitive nerve stimulation (RNS) test in myasthenia gravis (MG) crisis.Methods: The various parameters of the RNS tests in 26 patients with MG crisis were analyzed.Results: In 18 (69%) patients, MG crisis is the first manifestation of MG. RNS tests were abnormal in 24 (92%) patients by decrement at low-rate stimulation in any of 4 tested muscles. Three patterns of abnormality were found: MG pattern (decrement at low-rate stimulation) in 23 patients; Lambert-Eaton myasthenic syndrome pattern in 1 patient; and cholinergic crisis pattern in 1 patient.Discussion: During MG crisis, the RNS test can serve as a rapid and sensitive diagnostic tool for MG in a majority of patients.
