This invention relates to a universal ECG monitor of cardiac signals with enhances possibilities of scanning. The prior art monitors of cardiac signals make possible either a short-time touching by fingers or by other part of the human body of the electrodes, or they are permanently for a long time by means of a chest belt or by other means attached to the human body, wherein, such means are impractical and non-emergency. The equipment according to the present invention is a universal ECG monitor of a compact and easily portable design, which monitor substitutes the prior art costly and with difficulty movable hospital equipment. Moreover, it is a very economical solution, which makes possible to obtain a complete set ECG curves, i.e. the 12-lead ECG, by means of one of the monitor subsequently moved into various positions, and so to scan signals from different parts of the human body.
