Self electrocardiogram acquisition device

An electrocardiographic device (40) comprises a central portion (31) and two side portions (33) that have respective conductive surfaces (1,3) configured as acquisition electrodes for receiving a raw electrocardiographic signal from a patient's (99) respective hands (98); an acquisition unit (25) electrically connected to the conductive surfaces (1,3), so as to receive the raw signal and configured for filtering it within a predetermined passband to obtain a filtered signal; a digitalization unit (18) connected to the acquisition unit (25), so as to receive the filtered signal, and configured for sampling it to obtain a digital signalized; a data interface unit (22) electrically connected to the digitalization unit (18), so as to receive the digital signalized, and configured for providing it so as it can be drawn; wherein the side portions (33) have a base surface (36) that is opposite to the conductive surfaces (1,3) configured to be arranged on a plane; a height (D) between a base surface (36) and the conductive surfaces (1,3) set between 1 cm and 8 cm, the side portions having a front edge (37) to be arranged distally with respect to the patient (99) and in such a way that the distance between the front edge (37) and the conductive surfaces (1,3) is shorter than a predetermined value (L), so that the patient (99), arranging the bases (36) on the plane (28), can cause the palm (97) of his own respective hands (98) to bear on the side portions (33), maintaining the hand palm (97) in contact with the conductive surfaces (1,3) and at the same time assisting the fingers (98") of the hands (98) to possibly rest on the plane (28). This way, by causing the hand palm to bear on the raised side portions allows to discharge a large part of the weight of the arm on the conductive surfaces substantially without any muscle tension and without any movement, which would affect the contact surface during the acquisition, and substantially without any noise associated thereto, so that a filtering passband can be chosen that has a lower limit value lower than in the prior art devices, which allows preserving a large part of the information content of the electrocardiographic signal.
