Pacemakers are surgically implanted, but with relatively low risk. This procedure is internationally recognized as the only effective and reliable method of treating slow arrhythmias. After decades of experience of domestic and foreign arrhythmia specialists, the procedure has been optimized and the risk has been reduced to a very low level, and the surgical procedure is very optimized. Nowadays, the method of axillary vein puncture is adopted, and after imaging, axillary vein puncture is adopted, which also avoids complications such as wire breakage in the future. During the implantation process, the use of electrical conduction also reduces the risk of capsular bag hematoma occurring, and with resuscitation equipment such as continuous cardiac monitoring and defibrillator, the possibility of intraoperative risk is relatively low. However, for individual critical patients, there is also the possibility of risk occurring during pacemaker implantation. In this case, if the patient’s heart rate is very slow, a temporary pacemaker is first implanted for escort, which can maximize the safety of the procedure.
