摘要： The present disclosure belongs to the technical field of artificial cardiac pacemakers, and particularly relates to a leadless left-bundle-branch pacemaker. The leadless left-bundle-branch pacemaker comprises a case and an implant core, wherein the implant core is coaxially arranged inside the case, and a head of the implant core can be rotated out from the inside of the case; the implant core has an implant end that can be rotated out from the inside of the case, and the length of the implant end rotated out from the inside of the case is greater than 10mm; and an end of the case corresponding to the implant end is provided with a fixing end for fixing the pacemaker. After the fixing end is fixed to the myocardial wall, the implant core is "screwed into" the interventricular septum and can be rotated out from the case with different lengths according to the thickness of the interventricular septum of each person, such that the head of the implant core is rotated into the subendocardial left-bundle-branch area of the left ventricle. In this way, the leadless left-bundle-branch pacemaker can synchronously pace the left ventricle, thus solving the problem of current leadless pacemakers being unable to achieve physiological pacing.
