The purpose of this study is to develop a systematic rehabilitation exercise program (rehabilitation exercise routine), focusing on the rehabilitation training of the upper limb on the implantation side after transvenous cardiac implantable electronic devices (CIEDs) implantation, and to explore its impact on the joint function of the implanted upper limb and the overall quality of life of patients. This study will conduct long-term follow-up by comprehensively using imaging examinations and relevant professional assessment scales, focusing on evaluating the clinical safety of this rehabilitation exercise routine, and simultaneously clarifying its improvement effect on discomfort symptoms (such as pain, stiffness, etc.) and functional abnormalities of the implanted limb, so as to provide scientific basis and practical guidance for the standardized rehabilitation of patients after transvenous CIEDs implantation.
