What does sudden cardiac death mean? What are the signs? Introduction to three causes and five precu

Sudden cardiac death is one of sudden death. In fact, sudden cardiac death will have some precursors. Here are three causes and five precursors that are easy to cause sudden cardiac death. I hope you can know more and take precautions.

First:

Before a heart attack, the body, such as the neck, back, scalp, palms or soles of feet, will sweat a lot. At this time, you should be vigilant and beware of sudden death. You'd better stop activities and rest, take drugs in time, and call the emergency call immediately if necessary.

Second:

In the absence of incentives such as intense exercise, staying up late, insomnia or illness, extreme fatigue occurs for several days, weeks or even months, accompanied by symptoms such as anxiety, insomnia and asymptomatic wake-up. At this time, heart problems should be considered.

Third:

Patients with heart disease often feel shoulder, neck, chin and arm pain, which is a signal of myocardial ischemia, because when myocardial ischemia pain is transmitted to the central nervous system of the brain, it will be reflected in the same level of spinal cord region at the same time.

Fourth:

The typical symptom before heart attack is sudden or unexplained heartbeat. Once ventricular tachycardia occurs, it is very likely to die suddenly in a short time.

Fifth:

Many patients with sudden cardiac death have gastrointestinal symptoms repeatedly before death. Many have no history of stomach disease before life, which is one of the signals of heart attack. Gastrointestinal discomfort is due to cardiovascular abnormalities. Blockage of arteries due to fat deposits will reduce or even block blood transmission to the heart, which can cause angina pectoris.

The three causes of sudden cardiac death are as follows:

1、 Malignant arrhythmia, common congenital genetic tachycardia, such as brugotha syndrome, such as idiopathic ventricular tachycardia, long QT interval syndrome, etc., manifested as sudden ventricular tachycardia, even ventricular flutter and ventricular fibrillation, leading to cardiac arrest. In addition, slow heartbeat can also lead to sudden death, such as third degree atrioventricular block.

2、 Acute coronary syndrome. Sudden occlusion of blood vessels, especially large blood vessels, and occlusion of the left main artery can cause cardiac arrest.

3、 Cardiomyopathy. Such as hypertrophic cardiomyopathy, sudden cardiac death caused by obstruction of ventricular tumor outlet.
