Typical heart attack symptoms
Don't "tough out" heart attack symptoms for more than five minutes. Call 911 or other emergency medical services for help. If you don't have access to emergency medical services, have someone drive you to the nearest hospital. Drive yourself only as a last resort, if there are absolutely no other options.
Heart attack symptoms vary widely. For instance, you may have only minor chest discomfort while someone else has excruciating pain. One thing applies to everyone, though: If you suspect you're having a heart attack, call for emergency medical help immediately.
