The invention discloses a controllable wireless cardiac pacemaker system with multi-electrode pacing, which belongs to the field of electrical stimulation medical devices. The wireless pacemaker system has four or more fixed hooks, the pacing electrode is positioned on the anchoring hooks of the implant device, as long as one of the fixation hooks is punctured in the myocardium, it can function asa pacing. The pacemaker system has an electrode 'compensation' function, and when a single electrode is lost, the other electrode is controlled to be used for pacing without performing a second operation. In addition, the pacemaker system employs a chip (e. g., 74 LS148 and the like.) that can control the number of uses of the electrodes remotely according to the actual clinical situation of thepatient, achieve simultaneous stimulation of the four electrodes, or three electrode stimulation, or both electrode stimulation, or any of the electrode stimulation, and the stimulation intensity is adjustable. The system of the invention increases the probability of the electrode targets to contact the myocardium, reduces the risk of perforation during implantation of the pacemaker, reduces the number of re-implantation of the myocardial necrosis patient, prolongs the service life of the implantation device, and the simulation intensity varies according to patients, and it has great referencevalue and application value to the active implantation device.
