Including a rapid heartbeat or feeling dizzy… symptoms that precede a heart attack
Specialized medical studies have shown that at least one out of 4 people is exposed to:heart attack(a potentially fatal defect in the heart system), and that regarding 250,000 deaths result from “sudden cardiac arrest,” a condition that kills a person every two minutes.
The consequences of “sudden cardiac arrest” can be remedied if it is treated within minutes, but the only effective treatment is the use of electric shocks.
The causes of unrest
It produces disturbances heart system It is an abnormal electrical activity in the heart, and it occurs at any stage of a person’s life, and it is the main cause of death for millions of people around the world.
Experiments have shown the effectiveness of the implanted defibrillator in the heart in treating 98% of cases of dangerous tachycardia that can cause “sudden cardiac arrest”.
The implanted defibrillator in the heart is an electronic device that monitors the heart continuously, and when the device detects excessive and abnormal acceleration in the heart, it immediately supplies the heart muscles with energy, which restores the heart to its normal beating state.
Stroke and seizure
A stroke is a sudden and unexpected stop of the heart from beating. In this condition, blood flow to the brain and other vital organs stops. Sudden cardiac arrest usually leads to death if not treated within minutes.
Sudden cardiac arrest differs from a heart attack. A heart attack occurs if blood flow to a part of the heart muscle is interrupted. The heart usually does not stop beating suddenly. However, sudden cardiac arrest may occur following or during recovery from a heart attack.
People most at risk of stroke
The risk of sudden cardiac arrest increases with age, along with the presence of underlying heart diseases such as heart failure, and the occurrence of a previous heart attack.
This is in addition to drug or alcohol abuse, a personal or family history of sudden cardiac arrest, or genetic disorders.
Men are two to three times more likely to be affected than women, and sudden cardiac arrest rarely occurs in children unless they inherit problems that make them vulnerable to it.
Causes of heart attack
Studies are still ongoing in an attempt to discover the true causes of sudden cardiac arrest and how to prevent them, including: Ventricular fibrillation (a type of heart rhythm disorder) which is the main cause of sudden cardiac arrest in most cases, during which the ventricles (the two lower chambers of the heart) do not beat normally. .
Instead, they quiver very quickly and erratically, causing the heart to pump little or no blood to the body. Ventricular fibrillation can be fatal if not treated within a few minutes.
There are also other problems with the heart’s electrical system, such as the rate of the heart’s electrical signals becoming too slow and stopping, as well as if the heart muscle does not respond to the heart’s electrical signals.
This is in addition to diseases that cause problems with the heart’s electricity, such as heart disease or coronary artery disease, severe physical stress, some genetic disorders, and structural changes in the heart.
other reasons
Among the causes is also physical stress, as certain types of physical stress can lead to failure of the electrical system of the heart. During intense physical activity, the hormone adrenaline is released, which can lead to sudden cardiac arrest in people with heart problems.
Very low levels of potassium or magnesium in the blood can also cause it, as these minerals play an important role in the electrical signals of the heart.
Also, genetic disorders, as some families have a predisposition to heart rhythm disorders, and this predisposition is inherited, that is, it is transmitted from parents to children through genes, so they become more susceptible to sudden cardiac arrest.
symptoms
The first sign of sudden cardiac arrest is usually loss of consciousness (syncope), and at the same time, the heartbeat (or pulse) cannot be felt.
Some people may have a racing heart or feel dizzy or light-headed shortly before they pass out.
An hour before sudden cardiac arrest, some people may experience chest pain, shortness of breath, nausea, or vomiting.
Sudden cardiac arrest is often diagnosed following its occurrence by excluding other causes of a person’s sudden collapse, as it occurs without warning, and the diagnosis is rarely made through medical examinations when it occurs.
