Many patients are not clear about the implantation of pacemakers and are therefore fearful of the implantation process. After testing the electrode parameters, the electrode is fixed with sutures, the pacemaker and electrode are connected and placed in the bag, and the subcutaneous tissue and skin are sutured layer by layer, so that the implantation process is completed. However, there are some patients with venous malformations, and such cases pose a great challenge for implantation.
