Precursors and manifestations of sudden death

Precursors and manifestations of self-help of sudden death. In recent years, with the increase of people's life pressure and the acceleration of life pace, we often hear the news of sudden death in news reports or among other people. Do you know the precursors and manifestations of self-help? Precursors and manifestations of sudden death 1

First, palpitation < P > According to the data, people who stay up late for a long time have a much higher probability of sudden death than ordinary people, because staying up late for a long time will lead to palpitation.

Our bodies are regulated by sympathetic nerves during daytime work, and our hearts have strong contractility, so that we can produce more oxygen and nutrients for people to work and study.

At night, you need to rest, which is mainly regulated by parasympathetic nerves. At this time, your heart rate is relatively slow, so you can save energy to maintain your normal life the next day.

But if you don't have a good rest at night, it will lead to sympathetic nerve excitement, sympathetic nerve disorder and palpitation. Being flustered for a long time will lead to sudden death.

Second, the body feels tired and weak for a long time

Generally, the body will feel weak and listless after staying up late or staying up all night. This is because our body has not been well rested for a long time at work, so we need to rest our body and brain through reasonable rest to recover our physical strength.

However, if your body still feels tired after getting enough rest, it may be myocarditis, which is often accompanied by heart pain. < P > Severe myocarditis will lead to sudden death. So when you have this situation, go to the hospital for ECG and further investigation.

Third, syncope

There are many reasons for syncope, such as epilepsy, hypoglycemia or heart disease. In most cases, syncope is caused by slow heartbeat or cardiac arrest, which leads to insufficient blood supply to the brain.

If you have frequent syncope, it is suggested that you go to the hospital for a regular physical examination. If necessary, you can do head MRI or electrocardiogram to further judge your symptoms.

4. Chest tightness and discomfort

If you feel chest tightness and discomfort after strenuous exercise, stop yourself to have a rest, otherwise it is likely to lead to sudden death.

Because a person's blood supply will be insufficient in some parts of the body to a certain extent after overwork and strenuous exercise, then the heart will be affected to some extent, which will lead to sudden death.

All sudden deaths do not happen suddenly, but are the result of long-term adverse accumulation. Before sudden death, the body will give many signals. When these warnings appear in the body, please seek medical treatment in time, and don't ignore them.

In addition, in order to prevent sudden death, we should not only maintain good living habits, but also take an active part in outdoor activities, keep a good sleep and combine work with rest. Precursors and manifestations of sudden death 2

1. Chest pain < P > Pain response is the most easily grasped and perceived signal among the symptoms of sudden death. When you feel severe, tight and crushing pain in your chest, and you feel suffocated, you should be vigilant. The typical manifestation of coronary heart disease is chest pain, which generally occurs behind the sternum, especially chest pain persists, so more attention should be paid to this kind of situation.

2, recent or aggravated chest tightness

If the chest tightness after exercise suddenly appears recently, it can be relieved after rest, suggesting that you may have coronary heart disease. If you have symptoms of chest tightness before, and the recent symptoms are aggravated, it means that the previously stable plaque may develop into large damage at any time, leading to the occurrence of acute myocardial infarction.

3. Palpitation

Irregular increase in heart rate is usually the result of tachyarrhythmia. Most arrhythmias are less dangerous and will not cause sudden death, but if they are frequent ventricular arrhythmias, there is a risk of developing ventricular fibrillation.

4. Bradycardia

The beating of the heart is initiated by a specific pacemaker cell. The function of the pacemaker cell becomes worse, or there is a problem with the electrical conduction function of the heart, which will lead to the slow beating rate of the heart, and in severe cases will lead to cardiac arrest. When the heart rate is less than 5 beats/min, the blood pressure becomes low, which is prone to long-term cardiac arrest, leading to sudden death.

5. Unexplained fatigue

Unexplained fatigue and fatigue, or accompanied by chest tightness and edema, should be alert to the occurrence of sudden death, which may be caused by myocardial injury such as myocarditis. Myocarditis is more common in young people, usually after 1~2 weeks of catching a cold, with symptoms such as fatigue and chest tightness, which can easily cause acute heart failure or severe arrhythmia. In this case, heavy physical activity should be strictly prohibited, see a doctor as soon as possible, and rest in bed.

6. Blackness in front of eyes and numbness in limbs

Stroke is also an important cause of sudden death. If you have blurred vision, ghosting, numbness and fatigue in one limb, or walking unsteadily, you should be alert to the occurrence of stroke.

7. Syncope

Syncope is an important precursor of sudden death, and most syncope is caused by the sudden slowdown or stop of heartbeat, resulting in insufficient blood supply to the brain. Sometimes syncope can recover after a few seconds, and if it can't recover, it will cause sudden death. In case of unexplained syncope, you should be very vigilant and find out the reason as soon as possible.

8. Repeated excessive sweating for a long time

Sudden sweating without exercise is also a signal released before a heart attack.

9. Severe blood pressure increase

For patients with aortic dissection, the symptom is severe pain, and the pain will be accompanied by severe blood pressure increase. Precursors and manifestations of sudden death self-help 3

1. Recently appeared or aggravated chest tightness < P > Sudden death often leads to chest tightness before death, especially for patients with coronary heart disease. When you have similar symptoms, it means that there is something wrong with your health. At this time, you must go to the hospital for treatment in time and pay attention to rest.

2. Palpitation

It is not normal if people begin to have frequent palpitations. Palpitation is a typical manifestation of heart problems and a sign of sudden death. Of course, it is normal for people to have occasional palpitations, but if people are accompanied by palpitations for a long time, it is definitely abnormal, which is one of the typical symptoms of sudden death.

3. Abnormal sweating

If a person's body suddenly starts to sweat a lot, including the scalp, palms and other parts, everyone must pay attention to it. This may be a signal before the onset of heart disease. For the sake of safety, it is best to go to the hospital for examination.

4. Syncope

Most syncope is caused by the sudden slowing down or stopping of a person's heartbeat, which is caused by insufficient blood supply to the brain. Sometimes, after a few seconds, a person's heart will resume beating, and if it can't recover, it will cause sudden death, so if a person suddenly syncope, he must be sent to a hospital for treatment and find out the reason.

5. Breath holding and shortness of breath

The regular beating of the heart depends on the regular stimulation of the weak electrical signal from its special tissue "sinoatrial node". If there is a problem in the generation and conduction of this electrical signal, the heartbeat will be too slow or too fast, resulting in arrhythmia, and in serious cases, it will cause sudden death.
