A pacemaker that has shifted a month after it was put in requires surgical adjustment. Pacemakers that have shifted a month after being installed are abnormalities that can occur after surgery and may be related to electrode dislodgement or strenuous exercise. Pacemakers are very sophisticated devices that can effectively improve the symptoms of arrhythmia. Pacemaker displacement can lead to pacemaker failure. It is therefore necessary to reposition the electrodes, which can only be done surgically. After the installation of the pacemaker, bed rest is required, try to take the left side lying position, and reduce the excessive activities of the right upper arm in the first 1~3 months, as violent back and forth, up and down, and left and right movements can induce the pacemaker to dislocate. In your daily life, avoid contact with any electrical appliances, stay away from high-power electromagnetic devices, and always seek your attending physician’s consent before engaging in strenuous sports. When there is a problem with the pacemaker or when there is an abnormality in your body, you must go to the hospital in time.
