Cardiac Arrest

Cardiac arrest is a sudden (in most cases, unexpected) loss of heart function, breathing, and consciousness. This emergency usually results from an electrical disturbance in the heart that disrupts its pumping action, stopping blood flow to the rest of the body. It is different from a heart attack, where blood flow to a part of the heart is blocked. Cardiac arrest may occur in the ED/A&E or a patient may be transported by ambulance to the emergency department already in this state. Treatment is basic life support, Automated External Defibrillator (AED), and advanced life support as taught in advanced life support and advanced cardiac life support courses. Cardiac arrest is not a condition that can be self-diagnosed. It requires immediate medical attention and diagnosis by a healthcare professional.
