One minute you’re chatting with someone, and the next, they collapse, unresponsive. It’s not a heart attack—it’s Sudden Cardiac Arrest (SCA). And without quick action, it can be fatal in minutes.
At Abic Healthcare Services, we believe that knowledge saves lives. That’s why we’re breaking down what Sudden Cardiac Arrest is, what makes it different from a heart attack, and what you can do if it happens to someone near you.
Let’s talk about it.
What Exactly Is Sudden Cardiac Arrest?
Sudden Cardiac Arrest happens when the heart unexpectedly stops beating. This is usually due to a malfunction in the heart’s electrical system. When the heart stops pumping blood, oxygen stops flowing to the brain and other vital organs.
If not treated within minutes, SCA can lead to death. According to the American Heart Association (AHA), about 350,000 out-of-hospital cardiac arrests happen each year in the United States, and sadly, about 90% of them are fatal.
Is It the Same as a Heart Attack?
No—and this confusion can delay help.
- A heart attack (also known as a myocardial infarction) occurs when blood flow to part of the heart is blocked, usually by a clot.
- Sudden Cardiac Arrest, on the other hand, is an electrical problem. The heart’s rhythm becomes chaotic (often a condition called ventricular fibrillation), and it suddenly stops beating.
That said, a heart attack can trigger SCA, but they are not the same.
What Causes Sudden Cardiac Arrest?
Several things can lead to SCA:
- Coronary Artery Disease – This is the most common cause. It narrows the arteries and reduces blood flow to the heart.
- Heart Attack – As mentioned, a heart attack can disrupt the heart’s electrical system.
- Cardiomyopathy – A disease of the heart muscle that makes it harder for the heart to pump blood.
- Congenital Heart Conditions – Some people are born with electrical abnormalities in their hearts.
- Electrolyte Imbalances – Low potassium or magnesium levels can trigger irregular heart rhythms.
- Drug Abuse or Severe Trauma – Stimulants like cocaine or severe blows to the chest can also cause SCA.
Sometimes, SCA happens in people with no known heart disease, which is why it can be so terrifying and sudden.
Warning Signs to Watch For
SCA often occurs without warning, but some people may experience:
- Chest discomfort
- Shortness of breath
- Heart palpitations
- Fainting or feeling lightheaded
However, the main sign of SCA is sudden collapse and unresponsiveness. There’s no pulse. The person isn’t breathing or moving.
At that point, every second matters.
What to Do If Someone Goes Into Sudden Cardiac Arrest
This is where YOU could save a life.
1. Call for Help Immediately
Dial emergency services (911 in the U.S., 112 in Europe, or your local number).
2. Start CPR
CPR keeps blood flowing to the brain and organs until help arrives. If you’re not trained in full CPR, hands-only CPR can still save a life:
- Place the heel of your hand in the center of the person’s chest.
- Place your other hand on top and push hard and fast (about 100–120 compressions per minute—think of the beat to Stayin’ Alive by the Bee Gees).
- Do not stop unless you are exhausted or someone with advanced medical training takes over.
3. Use an AED If Available
An Automated External Defibrillator (AED) can deliver a shock to restart the heart. These devices are often found in malls, airports, offices, or gyms.
They are designed for public use and will guide you with voice prompts. If you can get one quickly—use it immediately.
Why Early Action Matters
For every minute that passes without CPR or defibrillation, the chance of survival drops by 7 to 10%. After 10 minutes, survival is unlikely.
But here’s the good news: Immediate CPR and AED use can double or even triple survival chances, according to the Sudden Cardiac Arrest Foundation.
Can SCA Be Prevented?
While you can’t predict everything, you can reduce your risk. Here’s how:
- Know your heart health. Regular check-ups can detect heart disease early.
- Control risk factors like high blood pressure, high cholesterol, and diabetes.
- Stay active and eat a heart-healthy diet.
- Avoid tobacco and limit alcohol.
- Know your family history. Some heart conditions are genetic.
- If prescribed, take your heart medications regularly.
If you or a loved one has a known heart condition, talk to your doctor about getting an Implantable Cardioverter Defibrillator (ICD). It monitors the heart and shocks it back into rhythm if needed.
