Electrode assembly and wearable electrocardiogram detection device

The utility model discloses an electrode assembly and a wearable electrocardiogram detection device. The electrode assembly comprises a wearable part, a first electrode, a second electrode, a third electrode and a fourth electrode. The electrode assembly is improved based on the Nehb lead electrocardiogram electrode arrangement condition, the right lower limb ground wire electrode connected to the right lower limb is changed to be connected to the symmetrical position of the heart apex pulsation point of the left lower limb electrode relative to the middle line of the human body, so that the characteristic parts, connected with the electrodes, of the human body are relatively concentrated, and the electrodes are convenient to arrange; the first electrode, the second electrode, the third electrode and the fourth electrode are arranged on the wearing piece, so that the electrodes can be correspondingly contacted with the characteristic parts of the human body when a user wears the wearing piece, and the use is
