The best way to tell if you are having a heart attack is to call 911 or your local emergency services immediately. If you have any of the following symptoms, it is important to seek medical help right away: chest pain or discomfort, shortness of breath, nausea, sweating, lightheadedness, and pain in other areas of your upper body such as your back, neck, or jaw.
