A sudden feeling of pressure or squeezing in your chest can be frightening, especially when you’re at home and unsure what to do. You may see online claims about a “10-second trick” that can save your life, but there is no proven maneuver that can stop a heart attack within 10 seconds.
The most important step is much simpler: recognize the warning signs and call your local emergency medical service immediately.
The American Heart Association emphasizes that people who think they are having a heart attack should activate emergency medical services right away. Fast treatment can limit heart damage and improve the chance of recovery.
1. Stop What You’re Doing and Call for Emergency Help
If you develop symptoms that could indicate a heart attack, don’t wait to see whether they disappear.
Call your local emergency number immediately and explain that you may be having a heart attack.
If you’re in the United States, this means 911. In other countries, use the appropriate local emergency number.
Calling an ambulance is preferable to driving yourself because emergency personnel can begin assessment and treatment while transporting you.
2. Sit Down and Rest
While waiting for emergency help, stop physical activity and sit in a comfortable position with your back supported.
Avoid walking around, exercising, or trying to “push through” the discomfort.
The NHS recommends sitting and resting while waiting for emergency medical assistance.
3. Know the Warning Signs
A heart attack doesn’t always begin with dramatic chest pain.
Possible symptoms include:
- Pressure, squeezing, fullness, or pain in the center of the chest
- Discomfort spreading to one or both arms
- Pain or discomfort in the back, neck, jaw, or stomach
- Shortness of breath
- Cold sweating
- Nausea or vomiting
- Lightheadedness
- Unusual tiredness
Symptoms can vary between people, and some heart attacks begin gradually with relatively mild discomfort.
4. What About Aspirin?
This is where online advice can become confusing.
The 2024 American Heart Association/American Red Cross first-aid guidelines state that an alert adult with acute, non-traumatic chest pain may be encouraged to chew and swallow 162–325 mg of aspirin while waiting for emergency services, provided they do not have an aspirin allergy and have not previously been advised by a healthcare professional not to take it.
However, the American Heart Association also emphasizes that you should call emergency services first and should not take aspirin and then wait to see whether the pain improves. An emergency dispatcher can advise you about aspirin based on your circumstances.
Do not take aspirin if you’ve been told to avoid it or if you have a known allergy. If you’re unsure, follow the emergency operator’s instructions.
5. Don’t Try Internet “Heart Attack Hacks”
Avoid attempting unproven methods such as:
- Coughing forcefully to “restart” the heart
- Drinking water or special mixtures
- Taking random supplements
- Exercising to increase circulation
- Waiting for the pain to disappear
- Driving yourself to the hospital
None of these should replace emergency medical care.
6. If the Person Becomes Unresponsive
A heart attack can sometimes trigger cardiac arrest, which is different from a heart attack itself.
If the person becomes unresponsive and is not breathing normally, call emergency services and begin CPR according to dispatcher instructions. An AED (automated external defibrillator) should be used if one is available.
The American Heart Association notes that emergency dispatchers can guide people through hands-only CPR when appropriate.
The Most Important “10-Second” Rule
Forget the idea that there is a secret trick that cures a heart attack in 10 seconds.
Instead, remember this:
Suspect a heart attack → stop → call emergency services → follow the operator’s instructions.
Every minute matters because the longer the heart muscle remains without adequate blood flow, the greater the potential for permanent damage.
Final Thoughts
A heart attack is a medical emergency, not something that should be treated with a home remedy.
If you experience unexplained chest pressure or pain—especially when accompanied by shortness of breath, sweating, nausea, lightheadedness, or pain spreading to the arm, jaw, back, or neck—seek emergency medical help immediately, even if you’re not certain it’s a heart attack.
The safest life-saving action is not a 10-second trick. It is getting emergency care as quickly as possible.
