Heart Attack vs. Cardiac Arrest: Know the Difference and When to Use an AED

Imagine you’re out for a regular day at work or spending time with family and friends, and someone collapses suddenly, showing no signs of life. Knowing how to respond and understanding what’s happening could mean everything. One of the biggest misconceptions people have is about heart emergencies: a heart attack and sudden cardiac arrest (SCA) aren’t the same. And when it comes to saving a life, that difference matters.

Two Different Emergencies: Heart Attack vs. Sudden Cardiac Arrest

First, let’s break down a heart attack. When someone has a heart attack, a blockage—usually from a clot—cuts off the blood flow to a part of their heart. Think of it as a “plumbing” problem. The heart is still beating, but it’s not getting enough oxygen. Symptoms like intense chest pain, shortness of breath, and sweating are common, and the person is often awake and aware, though in severe discomfort. In these cases, getting them to medical help quickly is critical. But because the heart hasn’t stopped, an AED isn’t what’s needed in that moment.

Then there’s sudden cardiac arrest (SCA)—and this is where an AED comes in. SCA is an “electrical” problem: the heart stops beating altogether. The person collapses, becomes unresponsive, and loses their pulse instantly. Unlike a heart attack, there’s no time to wait for help. Without CPR and an AED to shock the heart back into rhythm, brain damage or death can occur within minutes. Every second counts.

Why Having an AED Nearby Matters

During a cardiac arrest, survival rates drop by about 10% for every minute without intervention. An AED, or Automated External Defibrillator, is designed to detect abnormal heart rhythms and deliver a shock that can help restart the heart. Knowing how to use one—and having it nearby—can truly be the difference between life and death.

Imagine this: if you’re at a school event, a crowded workplace, or even a family gathering, and someone goes into cardiac arrest, the outcome can be drastically different if there’s an AED on hand. With proper training and quick action, you could double or even triple their chances of survival. This is why public access to AEDs is essential in schools, gyms, offices, and community centers.

Personal Preparedness for a Safer Community

The fact is, SCA can happen to anyone, anywhere, anytime. Unlike a heart attack, it often strikes without warning, affecting people of all ages—even those who seem healthy. It’s a frightening reality, but being prepared gives us control in the face of the unexpected.
