Abstract: A method and system are presented for use in determining a patient's heart condition. First and second data are provided, where the first data is indicative of the patient's heart rate, and the second data is indicative of bioimpedance peak value during a cardiac cycle. A relation between a certain predetermined value and a product of the first and said second data is determined, where such relation is indicative of the patient's left ventricular condition, enabling to identify a left ventricular dysfunction.

Abstract: A method and system are presented for use in assessment of at least one cardiac parameter of an individual. An electrodes arrangement is applied to an individual's body, for applying an electrical field to the body and providing an electrical output indicative of a systolic impedance change and of a velocity of said change during a cardiac cycle. Also provided is additional data indicative of at least of the following conditions of the individual: a value of total peripheral resistance (TPR), a value of cardiac index (CI), and existence of the AHF condition.

Abstract: A medical instrument is presented. The medical instrument comprises a housing, a first communication utility in the housing for receiving input signal indicative of physiological signals, and a second communication utility for communicating with a computer. The housing is configured for removable installment in a compact disc drive bay of a computer.

Abstract: A method and a system for non-invasively determining at least one main cardiorespiratory parameter of an individual, such as the Stroke Volume, at least one parameter characterizing balance of the extracellular fluid in the body (such as the Index Balance), and for diagnostics of blood circulatory problems and/or failures of cardiac functions. The method for determining the main cardiorespiratory parameter comprises the steps of attaching at least two electrodes to the individual's body in a manner enabling to obtain electrical bioimpedance measurements of the whole individual's body, passing an alternating current with a stable and constant amplitude through the electrodes, measuring the integral bioimpedance as the result of the current flow; simultaneously separating an active component from the integral bioimpedance; calculating the cardiorespiratory parameter of the individual from the obtained active component, using an empiric formula applicable to integral bioimpedance measurements.

Abstract: A medical device, utilizing a non-invasive method for determining the main cardiorespiratory parameters of a patient's body, and employing a method of operation wherein two or four electrodes are applied to the patient's body in a manner enabling integral bioimpedance measurements of the total body of a patient to be effected. High stability amplitude alternating current is passed through the electrodes into the body so as to obtain an integral impedance curve of the body and derive therefrom simultaneous automatic separation of an active component. The desired cardiorespiratory parameters of the body are calculated from the active component of the integral bioimpedance, using empiric formulae applicable to integral bioimpedance measurements; the calculation being accomplished based on the average data obtained during a respiration cycle.
