The invention relates to the technical field of steering wheels, in particular to an electrocardiogram steering wheel. The electrocardiogram steering wheel comprises a steering wheel body, a silicon rubber case is connected to one side of the steering wheel body which comprises multiple grips, a chuck body is arranged on one side of each grip, an insertion plate is arranged on the back sides of the chuck bod, through holes are formed in the two sides of the insertion plate, an insertion column is arranged on the lower portion of the insertion plate, a spline groove is formed in the inner sideof the insertion column, the silicon rubber case comprises a trumpet-shaped sleeve, connecting pieces are arranged on the two sides of the trumpet-shaped sleeve respectively, multiple key ports are formed in the side faces of the connecting pieces, and an arc-shaped sleeve is arranged at one end of each connecting piece. Accordingly, electrode slices and the silicon rubber case are subjected to injection moulding together, clamped to the steering wheel and connected to an electrocardiogram detection mainboard in the insertion plate through a lead wire, the two hands hold the grips and fit theexteriors of the electrode slices, and the electrocardiogram detection mainboard collects signals through the electrode slices and performs real-time transmission; therefore, self-inspection is conducted on time conveniently, health of the heart is guaranteed, and a person is escorted persistently.
