Firstly, the rescue approach for cardiogenic sudden death is the same regardless of the cause, whether it is rheumatic heart disease, coronary heart disease, malignant arrhythmia, or any other reason. If cardiogenic sudden death occurs, the rescue method is the same, which is to urgently perform cardiopulmonary resuscitation (CPR). CPR includes chest compressions of at least 100 per minute, and these must be effectively carried out. Secondly, artificial respiration must be performed, at about fourteen to fifteen times per minute. These two measures are the primary measures in the rescue of cardiogenic sudden death caused by rheumatic heart disease.

Golden hour for emergency treatment of cardiogenic sudden death

Cardiac arrest is now also a very frequent event. We have seen some reports of it occurring frequently at airports, train stations, and on public transport, involving middle-aged, elderly, or even young individuals. The golden window for emergency aid is 4 to 6 minutes, with shorter times being preferable. We say time is life because after 4 to 6 minutes, if effective circulation isn't restored, brain cells begin to die. Even if later resuscitation restores breathing and heartbeat, the individual may end up in a vegetative state. Therefore, within the shortest time frame of 4 to 6 minutes, external chest compressions, including opening the airway and artificial respiration, must be administered. The optimal window is 4 minutes, but no more than 6 minutes.

Can an electrocardiogram be used to check for sudden cardiac death?

Can an electrocardiogram (ECG) detect the potential for sudden cardiac death in the future? Sudden cardiac death cannot be detected by an electrocardiogram. An ECG can only identify conditions such as myocardial infarction, arrhythmias, or premature beats occurring at the time of the test. Sudden cardiac death is a sudden cardiac event that definitely cannot be predicted by an ECG. There are some risk factors for sudden cardiac death, such as high blood pressure, diabetes, and underlying diseases like coronary heart disease, which make individuals more susceptible to sudden cardiac death. We cannot rely on an ECG to predict it.

Does sudden cardiac death have a relationship with hypertension?

Sudden cardiac death and hypertension are related, with the most common cause of sudden cardiac death being acute myocardial infarction, which leads to malignant arrhythmias, such as ventricular fibrillation, resulting in sudden cardiac death. In addition, severe aortic dissection can also cause sudden cardiac death, and hypertension is often an important cause of coronary heart disease, acute myocardial infarction, and aortic dissection. Long-term hypertension can lead to the occurrence of arteriosclerosis, resulting in the formation of arterial plaques or aneurysms, such as those occurring in the coronary arteries, causing coronary heart disease and myocardial infarction, or in the aorta, often leading to the formation of aortic aneurysms. When an aortic aneurysm ruptures, it can cause aortic dissection.

Cardiogenic sudden death is often caused by what reasons and how to avoid it?

The most common cause of sudden cardiac death is currently acute myocardial infarction caused by coronary heart disease. The following measures can often effectively prevent sudden cardiac death: First, maintain good lifestyle habits, such as a low-salt, low-fat diet, maintain good emotional health, avoid extreme emotions, quit smoking, limit alcohol consumption, and regular exercise is important. Second, active pharmaceutical treatment, such as in cases of hypertension, hyperlipidemia, or diabetes, should be under the guidance of a doctor. It is crucial to use prescribed medications to lower blood pressure or blood sugar levels and control high blood pressure, high cholesterol, or high blood sugar. Actively managing these conditions can effectively prevent the occurrence of coronary heart disease.

The difference between sudden cardiac death and myocardial infarction

Sudden cardiac death and myocardial infarction are both types of coronary heart disease, but they are different from each other. Firstly, having a myocardial infarction does not necessarily result in sudden death. Myocardial damage involves a large area of necrosis in the heart, and the patient may experience symptoms such as chest tightness, shortness of breath, chest pain, and sweating. The main symptom of sudden cardiac death is the abrupt cessation of vital signs, with breathing and pulse disappearing. This condition can be caused by a large and extensive acute myocardial infarction, but it can also be caused by other reasons such as electrolyte disturbances or malignant arrhythmias, which are different causes.
