Abstract: A method for autonomic nervous system sensitivity-point testing on a skin of a patient is described. The method includes generating an electrotherapy signal that stimulates a vagal response of an autonomic nervous system of the patient when the patient is tested. The method further includes providing an electrically conductive tip that electrically contacts but does not puncture the skin when the patient is tested and coupling the electrotherapy signal to the electrically conductive tip.

Abstract: An electrical apparatus includes a battery, a circuit adapted to generate a periodic signal, and a wireless radio transceiver. The electrical apparatus further includes a control circuit adapted to set a characteristic of the periodic signal. The characteristic is received by an input of the wireless radio transceiver. The electrical apparatus further includes a first electrically conductive electrode adapted to electrically contact and puncture a first portion of a surface when the periodic signal is injected below the first portion of the surface. The periodic signal is coupled to the first electrically conductive electrode.

Abstract: Methods for caring for a patient are disclosed. In some embodiments, the methods include measuring a first autonomic nervous system condition of the patient, calculating a first autonomic dysfunction based on the measured first autonomic nervous system condition, and calculating a first sympathovagal balance based on the first measured autonomic nervous system condition. The method also includes treating the patient, measuring a second autonomic nervous system condition of the patient, calculating a second sympathovagal balance based on the second measured autonomic nervous system condition, and comparing the second sympathovagal balance with the first sympathovagal balance. The method also includes calculating a second autonomic dysfunction based on the measured second autonomic nervous system condition, and comparing the second autonomic dysfunction with the first autonomic dysfunction.

Abstract: Embodiments of the present invention provide a method, a system, and a computer code for analyzing the state of a first system (e.g., the autonomic system) from a time-varying signal representing a chaotic series of time intervals between quasi-periodical events produced by a second system (e.g., the cardiac system) governed by the first system. In one embodiment, the method includes extracting envelope information from the time-varying signal, constructing a phase space for the time-varying signal, extracting information on the relative positions of points corresponding to the time-varying signal in the phase space, combining the envelope and the position information and, based on this combination, providing information on the state of the first system.
