After pacemaker implantation, it is not advisable to move the forearm on the side of the implanted pacemaker significantly within six months (general movement is not a problem), but it is possible to move it in a small area to prevent the formation of thrombosis, especially in elderly patients. Do not touch the pacemaker site all the time, as there have been cases of nervous patients who often fondled the pacemaker buried in the skin of the chest, causing the pacemaker to become a turntable that rotates and dislocates the electrode leads, resulting in pacemaker dysfunction (known as the spinning syndrome). After pacemaker implantation, the local wound is usually compressed with a small sandbag for 4 to 6 hours, and after 24 hours the doctor will change the medication and observe the condition of the wound. Since pacemaker implantation is less invasive, the postoperative pain is usually not significant, and in some cases analgesic medication is required. In general, patients can move around after surgery and are not required to rest in bed. The temporary pacemaker requires a left lateral position because the electrode leads are floating in the cardiac cavity, as the right lateral position may cause the electrode leads to dislodge due to gravity, resulting in poor perception and/or pacing, whereas the head end of the electrode leads of the permanent pacemaker is fixed to the myocardium and the position does not have any adverse effects. The postoperative diet also returns to normal immediately after the procedure and does not require any special restrictions, but light and easily digestible food should be preferred. Since the pacemaker parameters are set using a dry reed switch, magnets should be avoided near the pacemaker site, such as radios, magnetized cups, etc. Cell phones should also not be placed in the breast pocket on the side where the pacemaker is buried and should be listened to with the opposite hand and ear when making phone calls, at least 15 cm away from the pacemaker. After pacemaker implantation, most of the physiotherapy devices should be avoided. If you have to use electric knife or electrocoagulation, please use the bipolar mode, program the pacemaker to bipolar sensing, VOO or DOO mode, strengthen the ECG monitoring and adjust back to the original pacing mode as soon as possible after the operation. What should I pay attention to after discharge from the hospital? When you come to the clinic for a review after the pacemaker implantation, usually around one month, you will be given a card, which is equivalent to a pacemaker ID card and should be kept in a safe place, preferably with a copy in case of loss. The card will contain information such as the type of pacemaker implanted, the number of years the pacemaker has been in operation, the name of the hospital where the pacemaker was implanted and the doctor. As long as you carry the card with you wherever you go, the pacemaker follow-up doctor at each hospital will know the type of pacemaker you have and the main information about it, and will be able to check the status of your pacemaker by telemetry. You should carry this card with you when you travel by air, because the pacemaker in your body will alert you when you pass through the security gate, so presenting this card when you go through security will prevent the security personnel from approaching your pacemaker with a probe and reduce some unnecessary troubles. Pacemakers are highly sophisticated instruments with more than 5,000 components per square centimeter of circuitry, and even though they have been closely tested before leaving the factory, they still need to be checked regularly to make sure they are functioning properly and that they are working in a way that meets your individual treatment needs. This is a very important task that must not be overlooked. At the time of pacemaker implantation, your doctor will set the programmed parameters according to your condition. Since your condition may change over time, you will need to visit your clinic regularly to adjust your pacemaker to your individual needs. These visits include a physical examination, ECG, and external programmable pacemaker parameters. If necessary, an ambulatory ECG, echocardiogram and chest radiograph will also be performed. It is generally recommended to follow up once in the first month after discharge and every 2-3 months from the second month to six months. After six months, follow-up can be done every six months to one year until the end of the life expectancy of the pacemaker. After that, the follow-up can be shortened to once every 2-3 months or even once a month. If the battery is close to depletion, it should be replaced in hospital. The follow-up interval should be shortened if problems are found during the follow-up.
