What Is the Difference Between a Pacemaker and an ICD?
Implantable internal defibrillator (Auto-I mplanted-C adiac De fibrillator, AICD). Implanted in patients with malignant arrhythmia, used to detect ventricular fibrillation and apply electric shock directly to the heart to stop the fibrillation. And resume normal working device.

- It is well known that about half of the deaths of patients with heart disease are sudden deaths (ie sudden deaths). The most common cause of sudden death is severe ventricular arrhythmias, such as ventricular fibrillation and ventricular tachycardia. These severe arrhythmias are often unpredictable, and medications cannot completely prevent them. These arrhythmias must be terminated immediately when they occur, but even in hospitals, sometimes they are too late to be treated. Because when ventricular fibrillation occurs, the heart can't actually eject blood, and fainting occurs after cerebral ischemia for more than 6 seconds. If the heart stops ejecting for more than 5 minutes, the chance of successful rescue is less than 20%. ICD is an instrument used to terminate these severe arrhythmias at any time. A large number of studies have shown that ICD implantation is much more effective than drug treatment. The appearance of ICD is similar to that of a pacemaker, and the implantation site is basically the same, but ICD is larger than a conventional pacemaker. Usually, the ICD has only one electrode lead (implanted into the right ventricle). ICD can detect and judge the types of severe ventricular arrhythmias that occur in patients at any time and give different treatments, so as to achieve the purpose of terminating arrhythmia and saving patients' lives.
