摘　　要：BACKGROUND Currently,the implantation of permanent cardiac pacemakers entails mostly subclavian vein puncture,which is relatively simpler and easier to master.However,due to individual differences,some patients carry a narrow space between the clavicle and the first rib.If the range of activity of the upper limb is increased,the friction between the electrode wire and the bone gap leads to the breakage of the electrode wire,which is manifested by poor pacemaker perception and pacing.CASE SUMMARY A 68-year-old woman underwent permanent pacemaker implantation in our hospital because of third-degree atrioventricular block 6 years ago.At that time,the patient was recommended to have a dual-chamber permanent pacemaker implantation,and finally chose a single-chamber permanent pacemaker because she could not afford the cost.The patient has repeatedly lost consciousness for no obvious reason in the past 3 d,and went to our hospital for treatment.The chest X-ray showed that the pacemaker electrode was broken.After the patient was given a pacemaker electrode replacement,the patient did not continue to lose consciousness.CONCLUSION Because the electrodes implanted in the subclavian approach are close to the clavicle and the first rib,the pacemaker electrodes may wear out.If the patient loses consciousness again after the pacemaker is implanted,we should consider whether there is a pacemaker.The possibility of electrode breakage,and timely help the patient to replace the new pacemaker electrodes.
