Is the human heart stopped? Does it mean death?

Yes. If the heart stops beating for too long, the oxygen level in the blood is too low, causing a large number of brain cells to die due to lack of oxygen. It can cause memory loss and loss of physical function, and brain death.

So, after the heart stops beating, the brain can survive for a while, but only for a short time. It is an important organ of the human body, and when the heart stops beating, a person dies. The coronary arteries supply oxygen to the heart, and due to various factors such as high blood pressure, hyperlipidemia, and high blood sugar, the coronary arteries are narrowed, and chest pain occurs when the stenosis reaches 50%.

Cardiogenic chest pain usually occurs during exertion and lasts from a few minutes to more than 10 minutes and is relieved by rest. At this time, it is often not taken seriously, and if not treated in time, it often develops into a complete blockage and myocardial infarction occurs. Chest pain is often severe and can be complicated by arrhythmias, cardiogenic shock, heart failure, and even sudden death.

The mortality rate of patients is high, but some patients can still be saved if they can get to the hospital in time. If the onset of the disease is within a few hours, intravenous thrombolysis with drugs can be used, and if possible, a stent can be placed at the site of coronary artery stenosis or blockage to open the blood vessel.

There is also a large artery called the pulmonary artery that separates from the right ventricle of the heart, which sends the blood that flows back from the body to the heart to the lungs to "fill with oxygen" and then supply it to the body again. Due to some reasons, such as long-term bed rest and restriction of activity, blood may form blood clots in the veins, and the blood clots may fall off during activity and block the pulmonary arteries, causing chest pain, shortness of breath, cyanosis, and high mortality.

The current standard of death is brain death: that is, the brain has no electrophysiological activity. The brain tolerates ischemia and hypoxia for 3-5 minutes.

This means that the heart is brain dead 3-5 minutes after it stops beating. Even though there are now technological conditions that can create artificial respiration and artificial circulation. But there is little hope of surviving after 3-5 minutes.

To give you two concepts: 1 Clinical death, that is, the patient's heartbeat and breathing have stopped. This is close or superficial death, clinical death can be prevented and reversed Usually what we call sudden death refers to the sudden and unexpected clinical death of the patient.2 Biological death is the permanent brain death of the patient due to lack of oxygen, which is irreversible quack.

Not necessarily, the indicators of death are cardiac arrest, respiratory arrest, and irreversible straightening of the EEG.

Cardiac death is indeed an important marker of death, but in many cases, the brain, kidneys, and liver do not die when the heart stops beating.

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.

Because everyone's body is produced by body cells, and body cells rely on the blood vessels to transport nutrients to get fitness. And in order for Blood Night to move, it is necessary to have items, and the driving force is oxygen, and without oxygen, people will die, there is no doubt about it.

Everyone's heart and brain stop is death, so understand how they stopped, that is, there is no blood to transport nutrients to that side, so they stop exercising, and venous blood is transported by oxygen, so without oxygen, the heart and so on will lose their goods, stop, and die. So, in the final analysis, life depends on oxygen.

Human death, modern science should refer to brain death, death conditions in various forms, such as loss of consciousness but involuntary breathing, that is, the folk saying "poured gas", which shows that although the lack of concept of his nervous system has not completely died, if this sequence should actually be involuntary respiratory arrest to be regarded as real death, naturally at this time the heart may have stopped fibrillating earlier.

I thought it should be that the involuntary breathing has stopped, and the excellent people have really died. If the two human organs are divided into which one is broken first, it is natural to inhale first, the lungs do not Bo does not mean that the heart also stops, the heart and the dolphin pulse rate are connected, if there is no pulse rate, it means that the heart is not moving, and the rescue application of external work pressure forces the lungs to inhale to promote the recovery of the heart.

Even if the heartbeat and inhalation stop, it can be treated for a certain period of time. Generally speaking, the heartbeat is the source of power, and the heartbeat is not there without inhalation, and the jet lag is very small. Whereas, a person who dies of ventricular breath does not inhale the heartbeat increases the speed and stops the heartbeat due to the lack of oxygen to the brain.

Even with the addition of a human heart, it will not have a purpose! Unless it is a more serious heart patient who needs to have his heart replaced, there is no problem with other human organs, and the cardiopulmonary bypass of the human heart can be maintained for a period of time!

Generally, the heart stops beating first, and the brain also has a certain period of time, and the body temperature gets lower and lower.

Usually the heart stops beating first, and the brain dies for a period of time, and the body temperature gets lower and lower.

When a person dies, the brain dies first, no longer thinks and reacts, and then the heart stops beating.

When a person dies, the heart usually stops beating first, and then the brain dies slowly.

The brain can function for a few hours after death. Is this true? You can't believe it after reading it.

If the heart stops beating for about 5 seconds, the patient will have symptoms of blackening in front of the eyes and fainting, the patient will have symptoms of coma after stopping for about 10 seconds, convulsions will be accompanied by convulsions for about 15 seconds, respiratory arrest after about 30 seconds, and death if not rescued for more than 3 minutes.
