Pacing electrode dislocation is one of the common complications of pacemaker implantation, pacemaker electrode dislocation can affect the cardiac sensory system, it is recommended to consult the hospital in time, and ask for professional physician’s help to find the cause of dislocation electrode to re-install the dislocated electrode, and determine the dislocation of electrode through the symptom, electrocardiogram performance, X-ray, and pacemaker programmed control. 1. Some atrial electrode dislocations have no obvious symptoms, while some patients may experience weakness or even fainting after the dislocation of the pacing electrode. 2. ECG shows no pacing or intermittent pacing and abnormal perception. 3. X-ray fluoroscopy shows that the atrial electrode or ventricular electrode is free from the cardiac chamber, or the position of the electrode is significantly changed compared with the original one. 4. Pacemaker programmed to record sudden changes in threshold and perception. Combination of the above items to make the judgment of electrode detachment; the emergence of uncomfortable symptoms, please consult the doctor in a timely manner, so as to avoid delaying the condition.
