First of all, keep healthy and adhere to good living habits. Among them, the probability of sudden death of patients with chronic diseases such as heart disease, hypertension and diabetes is higher than that of ordinary people. Therefore, maintaining good living habits, quitting smoking and drinking, and avoiding unhealthy living habits such as overwork and emotional tension can fundamentally reduce the occurrence of such diseases. Patients who have already suffered from such diseases need to be actively treated according to the doctor's advice to remove the cause or delay the development of the disease.
Secondly, always pay attention to your physical condition. Most patients with sudden cardiac death will have "aura" before the incident. Many patients have premonitory symptoms days, weeks or even months before cardiac arrest, such as angina pectoris, shortness of breath or aggravated palpitation, irregular heartbeat, dizziness, chest tightness, extreme fatigue or other nonspecific discomfort symptoms. When these abnormal situations occur, it is necessary to go to the hospital in time to assess the risk of sudden death and take preventive measures in time.
Finally, take the initiative to prevent. People with EF value (the percentage of blood pumped by the heart per beat) of 40% or less have a significantly higher risk of sudden cardiac death, so it is necessary to pay attention to prevent sudden cardiac death at any time. Implantable cardioverter defibrillator (ICD) is an effective treatment to prevent sudden death, and its curative effect is better than antiarrhythmic drugs. Implanting ICD is like carrying an "emergency room" with you, monitoring and protecting your heart 24 hours a day to prevent sudden death. According to statistics, ICD can significantly reduce the incidence and mortality of sudden cardiac death, reduce the risk of sudden cardiac death by 80%, and also help to evaluate and deal with patients' arrhythmia, so patients with poor cardiac function can benefit more from it.
