Warning Signs of Heart Attack - If you have heart attack warning signs, you should:
1. Stop. Immediately stop what you are doing and rest.
2. Talk. If you are with someone tell them what you are feeling. If your symptoms are severe, get worse quickly or have lasted 10 minutes, get help fast.
3. Call Triple Zero (000)* now! Ask for an ambulance. Don’t hang up. Wait for advice from the operator. *If calling 000 from your mobile phone does not work, try calling 112.

If you are with someone who may be having a heart attack, take charge and follow the steps above. Stay with the person until an ambulance arrives.

With a heart attack, every minute counts. Too many people lose their lives because they take too long to call Triple Zero (000) for an ambulance to take them to hospital.
