The artificial pacemaker consists of three parts: the pulse generator, the battery and the electrode leads. Artificial cardiac pacing is a treatment method in which the heart is stimulated by pulsed current of a specific frequency delivered by an artificial pacemaker through wires and electrodes to cause a heartbeat instead of the pacing point of the heart. There are temporary pacing and permanent pacing. Generally speaking, pacemakers should be placed for life-threatening slow arrhythmias such as third-degree atrioventricular block and symptomatic sick sinus node syndrome. In recent years, pacemaker placement has also been used in the treatment of certain specific diseases, such as Q-T interval prolongation syndrome, hypertrophic cardiomyopathy, dilated cardiomyopathy and congestive heart failure, and has initially achieved good results. Patients with permanent pacemakers need to pay attention to the following issues in the postoperative period and in their daily life. At the beginning of pacemaker placement, the patient needs a period of gradual recovery and adaptation, and some patients may experience a certain foreign body sensation, which will slowly adapt over time. In the early stages, patients should not do excessive physical activity. The upper limb of the implanted side of the pacemaker should not be moved too much in the early stage to avoid dislocation of the electrode. Since the pacemaker is fully implanted, the patient can bathe, shower, and even swim. Most patients can resume their sexual life if there are no other contraindications. Patients can travel, travel by car, train, airplane or ship, etc. Airport security screening instruments have no effect on pacemakers, but pacemakers can trigger metal detection alarms, which should be explained to security personnel in advance and presented with a pacemaker ID card. Household appliances and electromagnetic fields Most household appliances are safe. Hair dryers, electric shavers, electric ovens, irons, electric fans, televisions, refrigerators, computers, vacuum cleaners, washing machines, food processors, etc. generally do not affect pacemakers as long as they do not leak, and can be used without worry. Newer microwave ovens also generally do not affect pacemakers as long as they are operated properly. Although modern pacemakers have anti-mobile phone interference function, pacemaker patients should still try to avoid cell phones near the pacemaker, preferably use the opposite hand when playing cell phones, and keep the distance between the cell phone and the pacemaker at least 15 cm. However, patients with pacemakers should stay away from strong magnetic fields and strong electric fields such as radio transmitting stations, TV transmitting stations, OB vans, transmitters, radars, motors, internal combustion engines, high-voltage electric fields, transformers, power plants’ generating plants, electric arc welding, and hospitals’ MRI machines. The CCTV surveillance systems installed in certain public places are also capable of emitting strong electromagnetic waves and affecting pacemakers. The electromagnetic radiation generated by some high-powered ramp elevators can also interfere with the electronic system inside the pacemaker, and patients should pay attention to this. Medical diagnostic equipment Generally, diagnostic X-rays do not affect pacemakers and are safe for CT examinations. However, high-energy X-rays for treatment, such as linear gas pedals and electron cyclotrons, can damage pacemakers to a large extent. Gamma rays used for deep tumor treatment generally do not cause damage to the pacemaker as long as the irradiation site is not near the pacemaker. Since magnetic resonance machines can emit powerful constant magnetic fields and large fugitive magnetic fields, as well as high-powered radiofrequency magnetic fields and gradient magnetic fields, which can affect the working state of the pacemaker, pacemaker manufacturers often emphasize that it is forbidden for pacemaker patients to undergo magnetic resonance examinations, and if such examinations are indeed required, the pacemaker should be tested and programmed in advance, and cardiac monitoring should be performed. Ultraviolet and infrared rays in physiotherapy do not usually affect the pacemaker, nor do massagers if they are not placed directly on the pacemaker, but short wave and ultrasound heat therapy should be avoided. Patients with pacemakers should avoid the use of electrocoagulation scalpels during surgical procedures.
