Pacemakers are most afraid of magnetism because the various function switches within the pacemaker are controlled by magnets, so patients with pacemakers implanted should try to avoid machines and environments that produce strong magnetic fields. By the same token, because the magnetic and radiofrequency fields generated during a magnetic **** vibration test can cause the frequency output of the pacemaker to exceed its limits and may even damage the pacemaker, it is contraindicated for patients with implanted pacemakers to undergo a magnetic **** vibration test.
Current can also interfere with the normal function of the pacemaker, and even damage the pacemaker, so it is not surprising that the fear of electricity. Generally speaking, household appliances such as televisions, DVD players, VCRs, video cameras, microwave ovens, washing machines, refrigerators, vacuum cleaners, irons, razors and other commonly used home appliances will not affect the function of the pacemaker; however, radios, televisions, magnetized cups and so on that have magnetic properties should be used as far as possible from the pacemaker for more than 15 centimeters. Other commonly used household power tools and non-professional radio frequency transmission devices, etc., if operated properly, generally will not interfere with the function of the pacemaker. If interference occurs, simply move quickly away from or turn off these appliances.
Some anti-theft devices installed at the entrances and exits of supermarkets, libraries, and other public ****places can cause the pacemaker output to be inhibited or temporarily switch to an asynchronous pacing mode when the patient is in close proximity to the device. Therefore, patients with pacemakers should pass through such entrance/exit security devices at a normal gait and avoid staying in this area.
Certain industrial appliances, such as arc welding, induction furnaces, and resistance welding, as well as high-voltage power lines, can produce enough electromagnetic interference to affect pacemaker function if they are too close together.
Many people now use cell phones, although some test data show that the mutual influence between the cell phone and the pacemaker is temporary, but should maintain the distance between the handheld cell phone and the pacemaker at least 15 centimeters or more, after the use of the cell phone will be placed in the implantation of the pacemaker on the opposite side of the, can not be placed in the chest pocket, or don't be in the distance of 15 centimeters away from the pacemaker outside of the waist belt, because the Cell phones can also transmit signals when they are on standby.
Additionally, electrically charged medical equipment can affect the normal function of the pacemaker when the patient comes in for review, such as treatments such as electrosurgery, electrocoagulation, radiofrequency ablation, ventilators, lithotripters, extracorporeal electric defibrillation, and transcutaneous electrical nerve stimulation. Diagnostic chest X-ray and fluoroscopy have no effect on pacemaker function. However, highly radioactive substances such as 60 cobalt or gamma rays should not be directly irradiated to the pacemaker. If the patient requires radiation therapy, the pacemaker should be lead shielded to prevent impaired pacemaker function. Finally, it should be emphasized that patients should have regular review of ECG to understand the pacing function, sensing function and driving function of the pacemaker. Chest radiographs should be taken to clarify whether the position of the pacing electrodes is normal or not, and the condition of the pacing power supply should be checked in time so that the power supply can be replaced at the right time. The patient should go to the hospital immediately for examination once symptoms such as dizziness, chest tightness, blackness and weakness occur to determine whether there is any occurrence of pacemaker dysfunction.
