Temporary pacemaker surgery takes about 20-30 minutes and permanent pacemaker surgery takes about an hour. There are two types of pacemakers: temporary pacemakers and permanent pacemakers. The implantation of a temporary pacemaker is relatively simple, with the electrodes placed in the right heart, and the procedure can be completed in about 20 to 30 minutes. The procedure for permanent pacemakers is more complex and takes about one hour for most patients, and may be prolonged for more difficult patients. Pacemakers are mainly used to treat patients with severe bradycardia. Temporary pacemakers are implanted quickly and can work quickly, and are the mainstay of overdrive treatment. In persistent bradycardia, a permanent pacemaker is implanted. Patients requiring pacemaker implantation should be thoroughly evaluated prior to the procedure, which should be performed by a cardiologist, and the duration of the procedure will depend on the patient’s condition.
