A pacemaker is a medical device used to control heart arrhythmias. This small device can be implanted in the heart to control the heartbeat by releasing an electric current when it becomes abnormal. Pacemakers are usually fitted when needed, as this reduces the risk of surgery, but some people undergo a complex procedure to implant a pacemaker for preventive purposes. Pacemakers are strictly controlled and require further check-ups and maintenance at a later stage to ensure that the patient's heart maintains a normal rhythm.
There are two general types of pacemakers: single-chamber and dual-chamber. In a single-chamber pacemaker, electrical impulses from the pacemaker are released on only one side of the heart, with the other side relying on natural rhythms to follow, while in a dual-chamber pacemaker, the pacemaker can control the heartbeat by releasing electrical impulses in the atria and ventricles separately. In addition, some pacemakers have a heart rate sensing feature that adjusts the release of electrical impulses to the patient's own heart rate. Regardless of the type, pacemakers can help patients restore a normal heart rhythm and improve their quality of life.
While pacemakers can be effective in controlling arrhythmias, they carry some risks. Surgery can lead to side effects such as infection or bleeding, and regular checkups are needed long after implantation. In addition, the batteries in pacemakers have a lifespan and need to be replaced regularly. However, as technology continues to evolve, pacemakers are being improved and refined. For example, some pacemakers have built-in sensors that can monitor the patient's signs at any time, allowing for more timely detection of abnormalities. In conclusion, pacemakers are a very important medical device that can help patients regain their health, but they also require patients and physicians*** to work together for effective management and maintenance.
