As medical technology continues to advance, many patients with heart arrhythmias are choosing to have a pacemaker installed. With this small device, it is possible for heart patients to enjoy a normal life. It is true that you can return to a good life after the pacemaker is installed, but it does not mean that you can get rid of it once and for all. Pacemakers may increase the chances of heart patients contracting sleep apnea syndrome. A new French study found that two-thirds of people with pacemakers suffer from sleep apnea syndrome. Dr. Patrick Levy, professor of physiology at the University of Grenoble, said, “A series of previous studies have shown that sleep apnea is not a common problem among pacemaker users, but the sensitivity of the methods used in these studies is not yet sufficient to radiate all cases.” Numerous studies have shown that people with sleep apnea syndrome are at higher risk for cardiovascular conditions such as heart attacks and strokes than the general population. Dr. Kenneth Allenbogen, director of the Electrophysiology Laboratory at Virginia Confederate University and spokesman for the American Heart Association, said, “Heart patients should not think that if they get a pacemaker, they are safe from now on. We should think about the big picture, and doctors in particular should consider testing pacemaker users for sleep apnea problems.” New technology: magnetic resonance-compatible cardiac pacing technology The atrial and ventricular electrode leads of magnetic resonance-compatible cardiac pacing technology are active fixed electrodes, and patients implanted with this pacemaker are feasible for future examinations with various magnetic medical devices. Generally the work of the pacemaker is stabilized after the patient is discharged from the hospital, but many patients often worry that the pacemaker will suddenly malfunction or stop working, and when this happens, the first thing we should do is not to put ourselves under psychological pressure.
