Why do people die when their hearts stop beating?

Modern medicine has proven that brain death is the hallmark of human death. In fact, at the beginning of the cardiac arrest, the patient is in a coma due to lack of oxygen to the brain, and if the heartbeat can be restored within a few minutes, it is entirely possible for the person to "come back to life". In many cases, the patient's heart stops beating, which is not death, and first aid should be taken to wake the patient from a coma.

There is no meaning in human existence, only there is love in the world, go and experience it, you will find how beautiful it is, when you have money, you can appreciate the beauty of the scenery, when you are old, live there and reminisce cong From the microscopic + objective point of view, human cells are constantly metabolized At a certain time, people will naturally grow old until the limit People will be born Subjectively, it also has a lot to do with the mind Hurry up to the fire == The body and mind will be damaged. You're going to die sooner, and you're going to have 90 years to live, and you're going to end up with your loved ones leaving you, and you're not going to be in this world anymore, and you don't want to live anymore, because people get old, and people die because of chromosomes. Man is a part of nature, if nature is a living body, man is a kind of cell of it, normal cells will die because of metabolism, if there are immortal cells, nature will be dangerous.

There are also immortal cells in the world that have mutated to get rid of their metabolism, and that is cancer cells. As for the meaning of life, from the perspective of consciousness, people live to be happy, just like some people want time to slow down when they are happy, and hope that time will slow down when they are unhappy, and if they lose the confidence that they may be happy in the future, they would even prefer to die. Because everyone's path to happiness is not exactly the same, everyone's way of living is different.

Because our body is made up of cells, and cells rely on the blood to transport nutrients to move. And for blood to flow, it needs something, and the power is oxygen, and without oxygen, people will die, that's for sure.

If our heart stops and our brain stops, it is death, and then we know why they stop, that is, there is no blood to transport nutrients there, so we stop moving, and blood is transported by oxygen, so without oxygen, the heart and so on lose something, stop, so we die. So in the final analysis, life depends on oxygen.

Human death, modern medicine should refer to brain death, death phenomenon in many forms, such as loss of consciousness but involuntary breathing is still there, that is, the folk say "inverted breath", which shows that although the loss of consciousness his nerves have not completely died, if this sequence of meaning should be involuntary respiratory arrest is the real death, of course, at this time it is estimated that the heart has already stopped beating.

I thought it was supposed to be that the involuntary breathing stopped, and the person really died. If the two organs stop first, of course, the breath first, the lungs do not stop does not mean that the heart also stops, the heart is connected to the dolphin pulse, if there is no pulse, it means that the heart is not moving, first aid uses external pressure to force the lungs to breathe to promote cardiac resuscitation.

For example, China regards cardiac death as a medical death, while the United States uses brain death as a medical death.

Even if the heartbeat and breathing stop, it can be rescued within a certain period of time. Generally speaking, the heartbeat is the driving force, and the heartbeat is gone when it is out of breath, and the time difference is very small. In the case of a person who dies of asphyxiation, the heartbeat increases without breathing, and the heartbeat stops due to the lack of oxygen to the brain.

Even if you add an artificial heart, you won't be conscious! Unless it is a serious heart disease that needs to be replaced, there is no problem with other organs, and the artificial heart cardiopulmonary bypass can be maintained for a period of time!

When a person dies, the brain dies first. Because the brain is the control center, if the brain dies, the heart will stop beating later.

With the development of medical technology, patients' vital signs such as heartbeat, breathing, and blood pressure can be reversed or maintained for a long time through a series of drugs and advanced equipment. However, if the brainstem is structurally damaged and destroyed, no matter what medical treatment is used, it will eventually lead to cardiac death. Therefore, compared with cardiac death, brain death appears to be more scientific and the criteria are more reliable.

The heart first stops beating, and then the brain dies, because when the heart stops beating, the blood cannot reach the brain, and finally the brain dies due to lack of oxygen.

It is the heart that stops beating first, because the person dies when the heart stops beating, then the brain dies, and finally until there is no breathing.

After the heart stops, there will be insufficient oxygen supply to the brain, and the brain will be deprived of oxygen for about 10 seconds, and the person will have impaired consciousness (that is, fainting).

And in this 10 seconds or so, there will be a tingling sensation in the heart, and there will be some pain in the arm muscles.

Theoretically, if you do not get effective rescue within 5 minutes, you will have irreversible conditions such as brain death.

After death, there may be some purple discoloration on the face (due to lack of oxygen).

That's the rough idea.

No. Once the cardiac arrest does occur, loss of consciousness occurs after only a few seconds due to the interruption of the blood and oxygen supply to the brain. Therefore, once cardiac arrest occurs, the patient remains unconscious.

When a human heart stops beating, the brain continues to function. In other words, the human brain becomes aware of the fact that it is dead.

According to reports, the study shows that when we die, we know we're dead because our brains are always working to make us aware of what's going on around us. This means that after death, even for a short period of time, people are still conscious, but they are basically "trapped" in their own bodies.

When the heart stops beating, the meaning is still there because the brain is not dead. Ultimately brain dead and unconscious.

Of course, it will continue, because human beings are living beings, they will die, and death is the final destination, but consciousness will not last long.

I think it's okay, because after death, the brain will work for a while, and consciousness is there.

In fact, people are completely unconscious after death, which is just a whimsical thing for many people.

When the heart suddenly stops beating, it is called cardiac arrest, not heart failure. Heart failure is a loss of heart energy, with symptoms such as difficulty breathing, breath-holding, and edema. If the heart doesn't beat, the person can't.

Yi Anning Pill is mainly used to treat coronary heart disease, angina, myocardial ischemia, hyperlipidemia, atherosclerosis, myocardial infarction, arrhythmia, arrhythmia, premature beats, ventricular fibrillation, atrial fibrillation, heart failure and other heart diseases. It has good effects on stroke hemiplegia** and after stent lapping**! Many people also take Tranquility pills to maintain their body.

1. Types of heart failure.

1. Acute heart failure.

Acute heart failure is caused by damage to the myocardium or the heart can not bear it, resulting in a decrease in acute cardiac output, an increase in the pulmonary circulatory system, and various surrounding resistance, causing acute pulmonary congestion, pulmonary edema and other disease symptoms. From the perspective of clinical medicine, acute heart failure is mainly manifested in two aspects: insufficient blood perfusion of body organs and cardiogenic shock, among which acute left heart failure is the most common.

2. Chronic heart failure.

Chronic heart failure refers to a state in which heart failure is presented continuously. Chronic heart failure presents with dyspnea, edema, and lack of energy, but these features do not occur together. Chronic heart failure in adults is mainly caused by coronary heart disease, hypertension, valvular disease, dilated cardiomyopathy and other diseases.

Article **2 II. Heart Failure**.

1. Acute heart failure.

After the diagnosis of acute heart failure is confirmed, intravenous morphine and cardiac inotropes will be used; Oxygen inhalation through a mask, nasal cannula and other methods. If the above methods are ineffective, the appropriate vasoactive drug should be selected according to the condition of pulmonary congestion; If the condition is severe and symptoms of shock appear, intra-aortic balloon counterpulsation, blood purification, ventricular machinery and other devices should be used to assist in the operation.

2. Chronic heart failure.

1）****。

Strictly control hypertension, diabetes and other diseases, use antiplatelet drugs and statin lipid-regulating drugs to prevent coronary heart disease, prevent and avoid the occurrence of heart failure to a certain extent, avoid heart infection, and maintain electrolyte balance.

2) Use of neuroendocrine inhibitors.

When using the drug, follow a gradual principle, slowly increasing the amount from a small dose to the maximum amount that the patient can tolerate.

Article **33) Frequency of detection.

People with heart failure should measure their weight and blood pressure every day and record them when they go to the hospital for follow-up visits, so that they can refer to the doctor so that the doctor can be more clear about the amount of medication that can be changed.

Conclusion: It's not terrible to have a disease, it's terrible to be uncooperative**, please be kind to your life!

Not only do I have high blood lipids, but I also have high blood pressure and coronary heart disease. Found out last year. Now I am much better, and I hope that my body can recover as soon as possible and continue to earn money and support my family. My friend recommended me to take Yi'an Ning Pills, and the effect of my consumption was quite good, so I continued to eat them.

Health first nourishes the heart, if there is a heart problem, there is no energy to do anything.

01 There is a special set of tissues in the heart, which is called the sinus node, the atrioventricular node and the bundle of His; His bundle is divided into many small branches like spider webs, which are densely packed in the muscles of the left and right heart chambers. It is through these tissues that the heart automatically sends signals that cause the heart muscle to be excited, thus causing the heart to beat.

The heart is a muscular organ in the human and vertebrate body and is one of the most important organs. Its main function is to provide pressure to blood flow, pushing blood through the blood vessels in the circulatory system, and moving blood to all parts of the body. The human heart is located in the middle of the chest and is about the size of a fist and weighs about 250 grams.

The heart is composed of myocardium, which can be divided into four chambers: left atrium, left ventricle, right atrium and right ventricle, of which the left ventricular wall is the thickest, and these four chambers are the only way for systemic circulation and pulmonary circulation.

The heart can beat from birth to the end of life without stopping because of its unique structure.

There is a special set of tissues in the heart, which is called the sinus node, the atrioventricular node, and the bundle of His; His bundle is divided into many small branches like spider webs, which are densely packed in the muscles of the left and right heart chambers. It is through these tissues that the heart automatically sends signals that cause the heart muscle to be excited, thus causing the heart to beat. The beating of the heart occurs on its own and does not depend on any other part of the body.

However, the speed of the heartbeat is controlled by two nerves: the vagus nerve makes the heart beat less often, and the sympathetic nerve makes the heart beat faster.
