Know the symptoms of cardiac arrest

Learn about cardiac arrest symptoms so that you can identify them early and try to avoid them. Remember: health always comes first.

Health is never a small matter. Therefore, it is important to know what the symptoms of cardiac arrest are so that you know how to act if they occur.

In addition, by learning to detect them, you can help doctors gather valuable information about what is happening and what to pay attention to.

What is cardiac arrest?

First of all, and before seeing the previous cardiac arrest symptoms, we must remember what it is. Well, cardiac arrest is that discomfort that occurs when the heart suddenly stops beating.

When this situation occurs, the blood stops reaching the brain, and, as a consequence, the body stops. However, it must be remembered that it is not exactly the same as a heart attack or stroke. In this case, the heart usually beats, although with less blood flow due to a blocked artery.

Symptoms of cardiac arrest

1. Trouble breathing

Scientifically it is known as dyspnea, and it is a symptom that has a higher incidence in people of the female sex. It does not have to be something immediate, but it can appear even months before we suffer a heart attack.

If you feel fatigued and have trouble breathing, be very careful because it could be a cardiac arrest symptom. Indeed, if you feel that you are exhausted without an apparent cause, go to the doctor as soon as possible.

2. Excess sweat

The sweat excessively is another symptom of a possible cardiac arrest. If you find that you sweat too easily without exercising, it may be a sign that your heart is in trouble.

If we have clogged arteries, pumping occurs with greater difficulty and requires more effort from the heart. This results in the appearance of more amount of sweat. This is a consequence of the body’s response, which tries to maintain body temperature.

3. Indigestion and vomiting

Although it may seem that there is no apparent relationship between heart attacks and digestive problems, there is. And it is that many times cardiac arrests are preceded by digestive problems that include nausea and vomiting.

Vomiting or nausea is unlikely to be a symptom of a heart problem. However, if you generally have an iron stomach and have not eaten anything weird, be very careful because you may be facing a more serious problem.

4. Chest pain

This is one of the easiest and most common symptoms of cardiac arrest. However, it must be borne in mind that this is not always accompanied by chest pain.

As indicated by the Spanish Society of Emergency and Emergency Medicine in this article, when patients feel chest pain, they should be transferred to a hospital where they can be adequately evaluated and assisted with specific treatment.

In any case, chest pain ( angina pectoris ) is usually an easy-to-recognize symptom. To identify it, it is a type of pain that feels like intense pressure on the chest, and that can drift to the arms and shoulders.

However, feeling chest pain does not only imply cardiac arrest; that is, it can be associated with other pathologies, so medical auscultation is essential.

5. Pain in the back and jaw

We can also notice pain in the back and jaw due to chest pain. These symptoms tend to appear more in women than in men, so if you notice that you suddenly feel these discomforts, go to the doctor immediately.

6. Stunned

Lightheadedness can also be one of the symptoms of cardiac arrest. The normal thing is that this is accompanied by dizziness that can increase.

The person loses balance and feels very overwhelmed in these cases. Therefore, it is important to remain calm and not make sudden movements.

Recommendations for symptoms of cardiac arrest

If you notice any of these symptoms and you know that they are not associated with something obvious, such as a diagnosed stress disorder, see your doctor so that he can determine the causes of these symptoms.

Prevention is key to detecting possible heart disease. Among the healthy habits indicated by the World Health Organization (WHO) to prevent cardiovascular and cerebrovascular accidents are: following a healthy diet, not smoking, exercising, and avoiding a sedentary life.

If you know the symptoms and detect them, you can prevent something as serious as cardiac arrest, one of the main causes of death in the world. Write down these signals that the body sends you, and it will be easier for you.
