What is Sudden Cardiac Arrest?

Cardiac arrest, also called cardiac arrest, means that your heart suddenly stops beating. This cuts off blood flow to the brain and other organs. It is an emergency and can be fatal if not treated immediately. 112 should be called immediately


Cardiac arrest is rapid and severe: you lose consciousness, have no pulse and cannot breathe. Just before it happens, there may be a feeling of tiredness, dizziness, weakness, shortness of breath. You may faint or have chest pain. But these are not always necessary. Cardiac arrest can happen without any warning signs.


Your heart has an electrical system that keeps it beating regularly. The heart may stop if the electrical signals turn into a rhythm that is chaotic or causes the heart to beat too fast. There are different types of arrhythmias and most are not dangerous. One, called ventricular fibrillation, is the most common cause of cardiac arrest. In this condition, the heart cannot pump enough blood to your body. In a few minutes, your life can be over.


Many people with cardiac arrest have coronary artery disease. Having coronary artery disease means less blood flows to your heart. This can lead to a heart attack that damages your heart’s electrical system.


Cardiac arrest can also happen for other reasons:

Severe blood loss or severe lack of oxygen

Intense exercise when you have a heart problem

Very high potassium or magnesium levels, which can lead to a fatal heart rhythm

Some genetically inherited rhythm disorders

Disruption of the structure of your heart. For example, an enlarged heart or changes caused by an infection.


A heart attack is damage to the heart tissue as a result of blocked blood flow. Cardiac arrest does not occur in every heart attack. In addition, if the damage is great in a heart attack, cardiac arrest may occur months or even years after the attack.


If you have coronary artery disease (This is the biggest risk.)


if you have ever had arrhythmia or cardiac arrest, or if it has been in your family

Smoking or drug use

If you have had one or more heart attacks and the damage is extensive

If you have diabetes, high blood pressure or heart failure

If there is obesity


If you experience sudden cardiac arrest, you need immediate treatment with a defibrillator, a machine that cuts off the chaotic rhythm by electrocuting the heart. This shock can sometimes cause your heart to beat normally again. But for it to work, it must be done within the first few minutes. First responders such as police, firefighters, and paramedics often have a defibrillator and know how to use it. In some public places, there is a type of automatic rhythm control machine called the AED that anyone can use.


The patient is followed closely in the intensive care unit. An attempt is made to find out what is causing your cardiac arrest and to treat the problem. If you have coronary artery disease, a procedure called angioplasty may be performed to open narrowed or blocked arteries in your heart. In addition, lifestyle changes and medications are recommended to reduce the risk of recurrence of the event.


This device is a small automatic defibrillator that a doctor can place under your skin to send an electric shock to your heart if he finds an irregular heartbeat. Your doctor may recommend this procedure if you have a serious heart condition or have had cardiac arrest before.
