Noninvasive profiling of the autonomic nervous system has been shown to have prognostic value in patients with myocardial infarction, CHF and diabetes. The ANSAR system (ANX 3.0, Philadelphia, PA) is a new commercially available system that utilizes respiratory rate, HR and BP to assess on-going sympathovagal modulation during various maneuvers known to evoke autonomic perturbations. Instead of using conventional Fast Fourier Transform for frequency domain analysis, a Continuous Wavelet Transform (CWT) is used to generate numerical and graphical data. The system calculates Low Frequency Area (LFA, analogous to LF Power) and Respiratory Frequency Area (RFA, analogous to High Frequency Power.) …

A 52 year-old man with a past medical history of an isolated seizure presented to the Veterans Affairs hospital complaining of weakness which was most prominent in the face and upper extremities. About 6 months prior to this admission he developed intermittent episodes of weakness when chewing and swallowing. He would often have to use his hands to close his jaw when eating or talking.
