What is preventive treatment (ICD) for sudden death?

Prevention and treatment of sudden death (ICD) refers to implantable cardioverter defibrillator, which is an effective treatment method to prevent sudden death. ICD is an electronic device that can identify and terminate malignant ventricular arrhythmia in time. It can automatically identify malignant ventricular arrhythmia such as ventricular fibrillation, and implement electric defibrillation within 10 second, saving patients' lives. According to statistics, sudden death prevention therapy (ICD) can significantly reduce the incidence and mortality of sudden cardiac death, and reduce the risk of sudden cardiac death by 80%.

ICD has many functions, such as pacing and defibrillation, and can provide different treatments for various arrhythmia, including anti-tachycardia pacing, low-energy cardioversion, high-energy electric shock defibrillation and anti-bradycardia pacing. For patients with high risk of sudden death, such as patients with a history of cardiac arrest, patients with organic heart disease complicated with persistent ventricular tachycardia, patients with symptoms of heart failure complicated with low cardiac function, patients with severe arrhythmia, and patients with a family history of cardiac arrest, doctors suggest choosing sudden death prevention therapy (ICD) to prevent sudden death. ICD can also monitor and protect the heart around the clock, and the monitoring data can be transmitted to the computer through remote equipment, so that doctors can know the working condition of ICD and the patient's heart rhythm at the first time, which is conducive to the evaluation and treatment of patients' arrhythmia and benefit patients with poor heart function more.
