In recent years, arrhythmias have become increasingly prevalent in urban areas, and statistics show that 80% of cardiac-related deaths are caused by severe arrhythmias. Slow arrhythmias, such as sinus bradycardia, sinus arrest, and atrioventricular block, can be restored by implanting a pacemaker to normalize the patient’s heart function. Despite the increasing number of pacemaker patients, clinical surveys show that many patients still lack scientific knowledge about this treatment modality. There are a number of misconceptions circulating in the community. Myth 1: Permanent pacemakers can be used forever and do not need to be replaced. Even permanent pacemakers cannot be used permanently. Pacemakers rely on the internal battery to work and have a certain service life. After the service life, if the battery is low, it has to be replaced again surgically. Since the pacemaker is an integrated machine, the battery cannot be replaced alone, but the whole machine must be replaced together. Myth 2: Pacemakers are implanted and have to be maintained by taking medication. The pacemaker itself is a therapeutic measure and no medication is needed or available specifically to maintain the pacemaker, but the patient should actively take medication to control the original heart disease. For example, hypertension, diabetes, coronary artery disease, etc. Myth 3: Pacemaker-installed arms cannot move and it is better not to do housework. Avoid hyperextension of the shoulder joint on the implanted side for a week after pacemaker implantation, especially for 1-3 days, to avoid dislocation of the pacemaker electrodes. From 2 weeks after the operation, the implanted arm should be elevated appropriately, but over-extension and large arm flings should be avoided as much as possible. Generally, after 3 months, you can move around normally and do some housework, which will not affect your normal life. Myth 4: You cannot take a flight when you go out. Patients with pacemakers have no problem to travel by airplane, but they may be detected when they pass the airport security gate, but it does not affect their normal travel. Patients with pacemakers with sleep mode on need to go to the hospital before traveling abroad and make the appropriate adjustments. Myth 5: It is dangerous to go out on a thunderstorm day. Thunderstorms do not affect the normal use of pacemakers. In case of strong lightning, the pacemaker will automatically adjust to a safe model. Myth 6: Household appliances such as microwave ovens, induction cookers, cell phones and telephones cannot be used. Pacemakers nowadays have greatly reduced the interference of external radiation and electromagnetic fields due to many improvements in the pacing electrodes and other aspects. You can use cell phones, telephones, televisions and other household appliances normally. When turning on microwave ovens and induction cookers, you can choose to leave or keep a distance of more than 1 meter. If you are overly worried about the use of cell phones, you can answer the phone with the opposite hand, for example, if the pacemaker is installed on the left side, you can choose to answer the phone with your right hand. Myth 7: You cannot do MRI. In the past, patients with pacemakers were forbidden to undergo MRI scans to avoid magnetic field interference affecting the normal operation of the pacemakers. The new MRI-resistant pacemakers and lead systems have been certified by the U.S. Food and Drug Administration, and patients in Shanghai can now have MRI-resistant pacemakers installed. Myth 8: It is better for female patients to have a child before installing a pacemaker. For young women of childbearing age who need pacemaker implants, early detection and intervention is more effective in controlling the condition in a timely manner. Installation at a young age is better than installation at an older age. Installation before childbirth does not interfere with childbirth and provides safer cardiac protection measures for childbirth.
