| Abstract: | Neurophysiologic monitoring, including quantitative EEG, transcranial Doppler (TCD) ultrasound and transcranial near-infrared spectroscopy (NIRS), can be of diagnostic value in neurocardiology—the study of dysfunctional brain-heart relationships. A new multivariate EEG technique bispectral analysis, enables the cardiologist to objectively and precisely document transient episodes of syncope and seizure. TCD permits precise determination of the nature and extent of cerebral hemodynamic irregularities, while NIRS detects frontal lobe imbalance in the delivery and consumption of oxygen. These powerful new neurophysiologic tools, coupled with traditional systemic hemodynamic and electrocardiographic measures, will undoubtedly improve the diagnostic yield in the complex determination of the causes of syncope and cardiac-based confusional states. |
