What is sudden cardiac arrest? Sudden cardiac arrest (SCA) is when the heart suddenly stops beating. This is a medical emergency that needs to be treated right away. SCA that isnt treated right away causes death (called sudden cardiac death.) But even with treatment, most people with SCA do not survive.The heart has a built-in electrical system that keeps it beating in a normal rhythm. In SCA, a problem happens with the electrical system.
This leads to an abnormal heart rhythm. The abnormal heart rhythm that happens most often in SCA is called ventricular fibrillation or v fib. In this rhythm, the lower chambers of the heart (ventricles) twitch, but do not pump blood.
SCA is different than a heart attack. In a heart attack, one of the arteries that bring blood to the heart gets blocked, and heart muscle dies. But the heart still beats.What causes sudden cardiac arrest? SCA is most likely to happen in people who already have a heart problem, whether they know about their heart problem or not. Heart problems that can cause SCA include:
This is important, because brain injury is the most common cause of death after SCA.Most people need a breathing tube. A breathing tube is a tube that goes down the throat and into the lungs. The other end is attached to a machine that helps with breathing.Your doctor will also look for the cause of your SCA and treat it, if it can be treated. To look for the cause, your doctor will do a lot of tests. These usually include:
Most people who survive SCA are also treated with an implantable cardioverter-defibrillator (ICD). An ICD is a device that goes under a persons skin near his or her heart. It can sense abnormal heartbeats and then treat them with an electrical shock.What will my life be like if I survive? It depends, in part, on what caused your SCA and how quickly it was treated. Some people recover completely from SCA without any long-term problems. But many survivors have long-term brain problems.SOURCE:up to date medicine

Heart problems that can cause SCA include:
- Coronary heart disease, which is when the arteries that bring blood to the heart get clogged with fatty deposits
- A heart attack
- Thickening of the heart muscle, called cardiomyopathy
- Other problems with the hearts electrical system
- Heart failure, which is when the heart doesnt pump as well as it should
- Certain lung problems
- A severe injury, drowning, or getting electrocuted
- Illegal drugs, such as cocaine, heroin, or methamphetamine (meth)
- Electrolyte problems Electrolytes are substances in the body (like sodium or potassium) that the body needs to work normally.
- Feeling their heart racing, skipping beats, or beating out of sync
- Trouble breathing
- Feeling weak or dizzy
- Cardiopulmonary resuscitation (CPR) CPR is a way to get blood and oxygen moving through the body of someone whose heart has stopped beating. It involves compressions, which is when another person presses hard and fast (over and over again) on the persons chest. This squeezes the heart and gets the blood moving again, although not as well as when the heart pumps blood on its own.
- Defibrillation This involves using a device to send an electrical shock to the heart. This shock can sometimes get a normal heart rhythm started again. Defibrillation has the best chance of working when it is done right away.

To look for the cause, your doctor will do a lot of tests. These usually include:
- An electrocardiogram (ECG or EKG) This test measures the electrical activity in your heart.
- A chest X-ray
- Blood tests
- An echocardiogram (or echo) This test uses sound waves to create a picture of your heart as it beats.
- Other imaging tests Imaging tests create pictures of the inside of the body.
