1.What is arrhythmia? The normal heart beats 60-100 times per minute. If the origin or conduction of heart impulses is abnormal, such as the electrical signal is stopped or delayed, the conduction is disturbed or the conduction speed is abnormal, it can cause the change of the normal rhythm of the heart, too fast heartbeat, too slow heartbeat and arrhythmia are all arrhythmia. 2, bradycardia can cause which symptoms bradycardia can cause weakness, easy fatigue, shortness of breath, dizziness, chest tightness, palpitations and transient loss of consciousness and other symptoms. Severe cases can threaten the life of patients. 3.What are the treatment methods of bradycardia? Drug therapy: Only used in emergency or temporary, the effect is poor and cannot be used as a long-term treatment. Pacemaker therapy is currently the best and most effective method internationally recognized for the treatment of bradycardia. 4. What is a pacemaker A pacemaker is an electronic therapeutic device implanted in the human body that restores the pumping function of the heart by distributing electrical impulses to stimulate the heart to beat. It is small in size, weighing 18 to 30 grams, and consists of a pulse generator and electrode leads. The pacemaker implantation surgery is not a big surgery compared to open-heart surgery. The pacemaker implantation surgery is very mature and safe. The pacemaker is buried in a small capsule under the clavicle, close to the skin. The whole procedure usually takes about 1 hour and you can be discharged from the hospital 3-7 days after the surgery and you can resume your normal life soon afterwards. 6. What do you need to pay attention to after the surgery? A. You need to stay in bed for 24 hours after the pacemaker implantation, you can turn over to the left side, and you can eat easily digestible and nutritious food during the bedtime, and you should not eat eggs, soy products and other easily flatulent food; you can get out of bed for a small amount of activities after 24 hours, and gradually increase the activities for 1 week; B. The stitches of the postoperative wound will be removed in 7 days, and you should avoid strenuous activities of the upper limbs on the pacemaker side for 3 months after the surgery C. If you feel any local pain, redness or swelling of the wound, you should go to the hospital immediately for examination. 7. Do you need to take other medications after the pacemaker? The pacemaker solves the problem of slow heartbeat, but if you still have coronary heart disease, hypertension and other conditions, you still need to take medications and follow up with the doctor. 8.Does the pacemaker have any influence on the common equipments in daily life? The electric appliances that you can safely use in your family life or daily work are: TV, hearing aid, radio, fax machine, vacuum cleaner, copy machine, hair dryer, stereo, iron, headphones, washing machine, computer, microwave oven, refrigerator, electric oven, electric stove, electric blanket, massage chair, car, motorcycle, etc. Please note that when using these equipments Do not switch on and off frequently. When you are close to the pacemaker, the work of the pacemaker will be affected by high-powered intercom, welding machine, metal detector, handheld electric drill, etc. If you are not comfortable with the environment, please leave it immediately. Equipment that seriously affects the work of pacemakers and cannot be approached include: high-voltage equipment, large motors, generators, radar, broadcasting antennas, equipment with strong magnetic fields, etc. 9.What do you need to pay attention to when taking transportation? There is no special restriction when taking transportation, just avoid the seat belt to press the pacemaker; when the vehicle is being serviced, you should not be close to the car engine that is being started with the machine cover open, if you are close, if you feel unwell, leave the place immediately, if it does not ease, you should go to the hospital immediately. 10.Does the airport security equipment affect your pacemaker? When you fly, a quick passage through the security checkpoint will not affect your pacemaker, but the metal detector will detect the pacemaker implanted in your body, so you need to show the “pacemaker identification card” to the staff in advance. 11. Do the security devices in supermarkets and libraries affect the pacemaker? Usually not. It is recommended not to lean or stay in the device, but to pass quickly. 12. Can pacemaker patients use cell phones? Patients with pacemakers can use cell phones as well as normal people. However, the electromagnetic waves from cell phones may affect the pacemaker, especially at the moment of switching on and off and when the power is switched on and off, when the electromagnetic wave signal is strong. Studies have shown that the use of a cell phone more than 15 cm away from the pacemaker does not affect the work of the pacemaker. If the pacemaker is implanted in the patient’s right chest, please use the ear on the opposite side of the pacemaker to answer the phone and do not put the cell phone in your jacket pocket or hang it on your chest. 13. Do medical devices affect pacemakers When you go to the hospital, be sure to tell your doctor that you have a pacemaker. Ultrasound, nuclear medicine, lung perfusion/ventilation scans, CT, X-rays, electrocardiograms, etc. do not affect the work of the pacemaker; magnetic resonance imaging (MRI), defibrillation, electrocautery, etc. can affect the work of the pacemaker and should be avoided. Currently some brands of pacemakers can already accept MRI scans, which will bring more convenience to pacemaker patients. 14. How long does a pacemaker last? It is a battery-operated device, so its service life is limited. Generally speaking, dual-chamber pacemakers last 6-8 years and single-chamber pacemakers last 8-10 years, depending on the type of pacemaker, the model, the individual patient and the procedure set by the physician. 15. Do you need regular check-ups? After the pacemaker is implanted, the doctor will have to check the working condition and the normal parameters of the pacemaker on a regular basis. Reminder: Patients should carry their pacemaker identification card with them! 16. What is a pacemaker identification card? The pacemaker identification card is equivalent to a pacemaker ID card, which contains your name, gender, pacemaker model, implantation date, surgeon, etc., so you should carry it with you. 17. What is ICD therapy ICDs, or implantable cardioverter-defibrillators, are mainly used in patients at high risk of sudden cardiac death, especially in patients with previous severe ventricular tachycardia and/or ventricular fibrillation, or in patients at high risk of future sudden cardiac death, such as patients with post-myocardial infarction cardiac insufficiency. The ICD can automatically identify ventricular tachycardia and ventricular fibrillation and deliver shock therapy to save the patient’s life. 18. What is triple-chamber pacemaker therapy A triple-chamber pacemaker is mainly used in patients with chronic heart failure with uncoordinated cardiac contractions. In heart failure, the heart enlarges and the ventricular muscles in various parts of the heart chambers move uncoordinated, resulting in a decrease in myocardial contraction and a decrease in ejection capacity, just like a group of people rowing a boat, if the pace is consistent and the force is directed to one place, they will move quickly. On the contrary, if each person works separately, the forces will be scattered and cancel each other out, and they can only spin in place. A three-chamber pacemaker can treat heart failure. It works by implanting one electrode lead in each of the right atrium, left ventricle and right ventricle, and by reasonably setting the pacing sequence and timing of the three electrode leads, the failing heart muscles will contract again in a coordinated manner to achieve the purpose of treating heart failure.
