What can you do if you witness someone have a heart attack and stop breathing?

Call 911. If you know CPR start it after calling 911. If there is an automatic defibrillator nearby send someone to get it or get it yourself. This will talk you through what to do. Even if you don't know cpr, doing chest compressions quickly (about 100 per minute) until help arrives may save someone's life. Better yet, learn CPR and take refresher courses every 2 years.
CPR. If their heart is still beating, they would need rescue breathing. If their heart has also stopped, they would need cpr. Calling 911 is necessary and they can sometimes talk you through this intervention if you are not trained to do this. If you want this training, you could take a CPR class with the heart association (among other organizations).
Start CPR. A witnessed cardiac or respiratory arrest is an indication to begin CPR and rescue breathing, while waiting for additional help. See the american heart association's website.

Ok, this might sound strange but can you stop a heart attack by just breathing deeply?

No. Heart attacks are caused by plaque rupture (little fatty deposits inside the blood vessels that feed the heart muscle). Once it happens, it is essential to open that blood vessel as soon as possible with medical interventions, so call 911! Read more...

You . You may be experiencing panic attacks. Panic attacks usually last ten minutes or less. Some possible symptoms which might make you think you are having a panic attack include: chest pain or chest tightness; a pounding or rapid heartbeat, rapid or difficult breathing, nausea, sweating or numbness / tingling in your lips or fingers/ toes. People often believe that they are having a heart attack during an episode of panic. Other symptoms can include feeling very afraid and / or anxious; trembling, feeling really hot or cold or feeling dizzy or faint. If a person wakes up in the middle of the night gasping for air then they might be experiencing sleep apnea. I can not diagnose you. You should see your doctor for a full medical evaluation, to ensure that these symptoms are not due to a medical condition. If you do in fact have panic attacks, there are medications which can be prescribed to help and you can also see a psychologist to learn ways to control or prevent these symptoms that do not require medications. Good luck. Read more...

To be checked right away for a heart attack. That means not waiting at home to see if it turns into a bad heart attack.
