The invention relates to a pacemaker electrode wire, which comprises a main electrode, an insulating sleeve and a plurality of annular electrodes coaxially arranged from inside to outside. The main electrode and the annular electrode are insulated from each other, an electrode contact is provided with a plurality of electrode contacts, the electrode contacts are electrically connected with one endof the main electrode and the annular electrode respectively, and the electrode contact is fixedly connected with one end of the insulating sleeve; and the other end of the main electrode is providedwith a head end electrode, the head end electrode extends out of the other end of the insulating sleeve, and the end part of the head end electrode is hook-shaped. The pacemaker electrode lead does not depend on X-ray fluoroscopy when the electrode lead is installed, so that the accumulated damage of the X-ray fluoroscopy to the body is avoided; in the installation process, guidance is conductedthrough real-time display of a three-dimensional mapping system, the operation is easy, testing is convenient, and safety and reliability are achieved.
