How do I know if I'm having a heart attack?
assistant
The most common signs and symptoms of a heart attack include chest pain or discomfort, shortness of breath, nausea, vomiting, sweating, lightheadedness, and pain in other upper-body areas, such as one or both arms, back, neck, or jaw. If you experience any of these symptoms and think you might be having a heart attack, it's important to seek medical help immediately.
