Heart failure - causes and first aid

In some cases, a person may have cardiac arrest, while cardiac activity stops completely, but bioelectric activity may be observed. When heart failure occurs in 90% of people, fibrillation of his ventricles is observed, in other cases - tachycardia, ischemia, myocarditis, hypoxia, hypothermia or cardiomyopathy. Most often, heart failure occurs in males over the age of fifty, with the cause of such a syndrome may be alcoholism, smoking, heavy stress on the heart.

The first sign of the cessation of cardiac activity is loss of consciousness, absence of a pulse on the arteries, breathing stops, cramps, eyeballs widen, their reaction to light is not present, skin pallor is observed. Thus, cardiac arrest symptoms are pronounced, which is a consequence of extinction of the vital activity of the human body.

Common causes of this syndrome are:

- the age of more than fifty years;

- diseases of the heart and blood vessels;

- smoking, drinking alcohol and drugs;

- hypothermia of the body, the presence of injuries by electric charge;

When there is a cardiac arrest, the consequences can be manifested in the cessation of blood flow through the vessels and arteries.

Before diagnosing a cardiac arrest, it is necessary to pay attention to the symptoms that precede this situation. So, a person can suddenly become pale, blood pressure drops quickly, the heart produces less than forty beats per minute, and the pulse becomes more than 120 beats per minute, there is a tachycardia. In all cases, the symptoms of heart failure syndrome are the same.

Treatment should be emergency. Since the most common cause of this phenomenon is cardiac fibrillation, it is necessary to perform defibrillation and chest compression to ensure the flow of blood flow into the artery. In this case, it is necessary to ensure the supply of oxygen to the lungs by carrying out artificial respiration. With a rapid response and carrying out resuscitation, it is possible to ensure the delivery of oxygen to the human organs, restore blood circulation, thereby avoiding death. Thus, with a properly organized activity to support the vital activity of the human body, one can save his life without the work of the heart for a long period of time, until the doctors arrive to provide medical assistance aimed at preventing irreversible changes in the cerebral cortex. Therefore, in such cases, as cardiac arrest, drug therapy is necessary.

The reason for the ineffectiveness of resuscitation is the loss of heart tone. In this case, you need to introduce into it a drug that can improve the tone of the heart muscle. For these purposes adrenaline is well suited.

In the event that after an hour after the compression and ventilation of the lungs, the heart does not start working, and the pupils remain wide, you can talk about the death of a person, so the resuscitation is stopped.

Thus, cardiac arrest is most often observed with ventricular fibrillation or asystole, while the person stops breathing, his pulse disappears, consciousness is lost. A common cause of discontinuation of this body is a disease such as myocardial infarction. In case of failure to provide first aid, a person dies in a few minutes. In many other situations, with the timely provision of assistance, it can be saved. Therefore, it is necessary to know what actions to take in case of cardiac arrest in someone from the surrounding people.
