What is Cardiac Arrest

Cardiac arrest


Cardiac arrest is a serious medical emergency that occurs when the heart suddenly stops beating. It is caused by an electrical malfunction in the heart, which disrupts its normal rhythm and causes it to stop pumping blood to the body. Cardiac arrest can happen to anyone, at any time, and without warning. It is a leading cause of death worldwide, and it is important to understand what it is and how to respond in case of an emergency.


When the heart stops beating, it can no longer pump oxygen-rich blood to the brain and other vital organs. This can lead to brain damage, organ failure, and death within minutes if not treated immediately. The most common cause of cardiac arrest is a condition called ventricular fibrillation, which is an abnormal heart rhythm that causes the heart to quiver instead of pumping blood.


Symptoms of cardiac arrest include sudden loss of consciousness, no pulse or breathing, and chest pain. If someone is experiencing these symptoms, it is crucial to call emergency services immediately and start CPR if trained. Cardiopulmonary resuscitation (CPR) is a lifesaving technique that can keep a person alive until emergency medical services arrive by circulating oxygen and blood to the brain and other vital organs.


Defibrillation is another essential emergency procedure that can be used to restore the normal rhythm of the heart. A defibrillator is a medical device that delivers an electrical shock to the heart, which can help to restore its normal rhythm. Public access defibrillator (PAD) are available in public places such as airports, malls, and other public places. These defibrillators are designed to be easy to use and include instructions on how to use them.


Preventing cardiac arrest involves taking steps to promote heart health, such as eating a healthy diet, getting regular physical activity, maintaining a healthy weight, and not smoking. Medications, such as blood pressure and cholesterol-lowering medications, as well as blood thinners, can also reduce the risk of cardiac arrest. In some cases, surgery may be necessary to prevent cardiac arrest. Angioplasty and coronary artery bypass surgery are two common procedures used to treat blocked or narrowed arteries that can lead to cardiac arrest.


Cardiac arrest is a serious medical emergency that occurs when the heart suddenly stops beating. It can happen to anyone, at any time, and without warning. Knowing the signs and symptoms, and how to respond, can save lives. Quick action, including performing CPR, using a defibrillator, and calling emergency medical services, is crucial. Additionally, making lifestyle changes, taking medications as prescribed, and undergoing surgery, can help to prevent cardiac arrest. Regular monitoring and follow-up with a healthcare provider is also essential.
