Aim:To study the role of neuro cardiac axis in central vertigo. Methods:This study is done in department of neurology, Coimbatore medical college hospital, Tamilnadu from January 2018 to September 2018. Inclusion Criteria:All patients presented with central vertigo were included. Exclusion Criteria:Patients presented with peripheral vertigo were excluded. All patients presented with central vertigo were undergone electrophysiological studies includes cervical vestibular evoked myogenic potential (cVEMP), Electroencephalography (EEG) and electrocardiography (ECG). Results:This study is done in 40 patients presented with central vertigo in the age group of 20–60 years, males (70%) mean age (46years), females (30%) mean age (43.6years). cVEMP–(P13 to N23) amplitude – mean in normal side (33.25µv), abnormal side (21.38 µv). Patient’s neuro cardiac axis was analysed using cVEMP, EEG and ECG. cVEMP showed statistically significant drop in (p13 to N23) amplitude (P<0.00001) and left axis deviation in ECG (P<0.00001). All patients with central vertigo showed normal EEG pattern. Conclusion:Electrophysiological evaluation of neuro cardiac axis using cVEMP, EEG and ECG is useful for early detection and treatment of central vertigo
