Signs of cardiac arrest

Cardiac arrest is when the heart suddenly and unexpectedly stops beating. It can happen to anyone, anywhere, at any age, often without warning.

  1. Sudden collapse

  2. Loss of consciousness

  3. Unresponsiveness to touch or sound

  4. Not breathing normally or making gasping sounds

When the heart stops beating, blood stops flowing to the brain and other vital organs. Brain injury can begin within five  minutes.

Only fast action – doing CPR and using an AED – can double the chance of survival.

Do you have a couple minutes? That's enough to learn the basics of CPR and how to use an AED. Watch our short video below.

Fighting to restart more hearts

Every second counts, a new Heart & Stroke report, reveals the critical state of cardiac arrest in Canada and how we can save more lives.

You are the person's best chance of survival.

 
Don’t wait for someone else to step up. Every second counts. Start CPR immediately.

 

Doing CPR – even if it’s not perfect – gives the person their best chance of survival.

 

Don’t wait for EMS to arrive – response times can be 6 or more minutes in urban centres and longer for northern and remote communities.

Who is at risk?

Cardiac arrest can happen to:
- anyone
- anywhere
- any time
- at any age
- often without warning.

 

The difference between cardiac arrest and a heart attack

Cardiac arrest and  heart attack are not the same thing, although people often confuse the terms. Both are medical emergencies.

Cardiac arrest

Heart attack

The heart suddenly and unexpectedly stops beating

The heart is not getting enough blood so it starts to die

Caused by an abnormal heart rhythm

Caused by a blockage of blood flow to the heart

The heart stops pumping blood to the brain and other vital organs

The heart continues to pump blood

It is a critical medical emergency

It is a medical emergency

Every minute without CPR or AED use decreases the person’s chance of survival by about 10%

Damage to the heart increases with every minute of treatment delay

Brain injury can begin within five minutes
