Cardiac arrest and heart attack are often used as if they mean the same thing, but medically they are very different. Confusing the two can delay the right action and cost a life. In this video, RN Academy explains the difference between cardiac arrest and heart attack in a simple and clear way that anyone can understand. A heart attack is caused by blocked blood flow to the heart muscle, while cardiac arrest is caused by a sudden electrical failure that stops the heart from beating. Knowing how to recognise each condition and respond correctly can save a life. This video is important for everyone — not just healthcare workers. Parents, teachers, students, coworkers, and bystanders all need this knowledge. Understanding when to call emergency services, when CPR is needed, and when an AED can help makes a real difference.
