Diagnostic value of electrocardiogram during routine electroencephalogram

Introduction: A single-lead electrocardiogram (EKG) is routinely recorded with electroencephalogram (EEG). This study investigates the frequency and types of EKG abnormalities during routine EEG.Methods: All EEGs (20–60 min) over one year were retrospectively analyzed. blinded cardiologist interpreted recordings. An epileptologist evaluated EEGs. Demographic data, underlying comorbidities, indications for EEG extracted.Results: total 433 recordings 365 patients included. Mean (±SD) age was 46.8 (±21.3) years 50.4% females. detected in 28.5% patients; sinus tachycardia (11%), premature ventricular contractions (7.9%), atrial fibrillation (Afib) (6.3%), bradycardia (2.2%) (1.1%). Afib more common females than males (p = 0.020), confirmed six out seven discovered 17 patients. Age (OR: 1.67, 95%CI: 1.05–2.66, p 0.031), prior diagnosis epilepsy 2.25, 95% CI: 1.22 – 4.14, 0.009), history seizure 1.97, 1.09–3.54, 0.024), abnormal 2.14, 1.25 3.66, 0.005) evaluating seizures/epilepsy 4.18, 1.32 13.21, 0.015) or syncope 3.21, 1.16 8.84, 0.024) independently associated EKG.Conclusion: The captured high, being most significant. Older age, seizure, EEGs, significant predictors. These findings suggest neurologists to become vigilant as such might have diagnostic therapeutic implications.
