WHAT TO DO IN A HEART ATTACK EMERGENCY?

If you encounter someone who is unconscious from a presumed heart attack, call for emergency medical help. If you have received training in emergency procedures, begin cardiopulmonary resuscitation (CPR). This helps deliver oxygen to the body and brain.
According to guidelines by the American Heart Association, regardless of whether you’ve been trained, you should begin CPR with chest compressions. Press down about 2 inches (5 centimeters) on the person’s chest for each compression at a rate of about 100 a minute. If you’ve been trained in CPR, check the person’s airway and deliver rescue breaths after every 30 compressions. If you haven’t been trained, continue doing only compressions until help arrives.
Sudden cardiac arrest during a heart attack is commonly caused by a deadly heart rhythm in which the heart quivers uselessly (ventricular fibrillation). Without immediate treatment, ventricular fibrillation leads to death. The timely use of an automated external defibrillator (AED), which shocks the heart back into a normal rhythm, can provide emergency treatment before a person having a heart attack reaches the hospital. But, if you’re alone, it’s important to continue chest compressions. If there’s a second person present, that person can look for a nearby AED.
