Abstract
Sistema electrónico para la medida de la impedancia eléctrica del tórax. El sistema objeto de invención mide la impedancia eléctrica del tórax, de modo que puede estimarse la pérdida de señal eléctrica del electrocardiograma convencional. Consta de los electrodos a situar en el cuerpo del paciente (1); circuito electrónico para simular una impedancia controlada por tensión (2); amplificador de instrumentación de ganancia variable y elevada impedancia de entrada (3); sistema de ajuste de la impedancia, detección de señal QRS y medida de picos (4); sistema de promediado del número deseado de medidas(5); display para la visualización de la medida (6) y un panel de control (7) que permite seleccionar las condiciones de medida. Esta invención se basa en considerar el corazón como un generador de señal y simular con (2) una impedancia equivalente a la de los tejidos interpuestos entre éste y el electrodo explorador, reconocible porque se reduce a la mitad la amplitud de la señal del ECG.Electronic system for measuring the electrical impedance of the chest. The system object of the invention measures the electrical impedance of the chest, so that the loss of electrical signal from the conventional electrocardiogram can be estimated. It consists of the electrodes to be placed in the patient's body (1); electronic circuit to simulate a voltage controlled impedance (2); variable gain instrumentation amplifier and high input impedance (3); impedance adjustment system, QRS signal detection and peak measurement (4); averaging system of the desired number of measures (5); display for the measurement display (6) and a control panel (7) that allows you to select the measurement conditions. This invention is based on considering the heart as a signal generator and simulating with (2) an impedance equivalent to that of the tissues interposed between it and the scanning electrode, recognizable because the amplitude of the ECG signal is halved.
