An ECG device comprising limb leads and chest wall leads is described which is also suitable for deriving the hemodynamic activity of the heart and the function of the vessels and, respectively, also for evaluating the fluid equilibrium. This is achieved in that at least part of the electrodes of the multichannel ECG is developed with additional embodiments for physical emissions and measurements, for example, electric current and voltage, pressure, sound vibrations, light, and that an electrode is provided for the current supply and, respectively, the voltage measurement at the upper thorax aperture. Furthermore, an alternating current field is built up between the electrodes or, respectively, the distance between the electrodes is used as an ion conductor. Thus, during the conventional ECG writing, the acceleration of the blood and hence the cardiac output, the valve closure and the valve opening, as well as the mechanics of individual circulation sections, for example, also the pulse wave transit time, the blood flow in body sections, the body composition etc. can also be registered and output simultaneously with the routine ECG. |
