6. Lightheadedness
Patients often describe feeling dizzy during a heart attack. Women may feel they are about to pass out, especially if they are doing any type of physical activity. Sometimes, lightheadedness is mistaken to be hypoglycemia or a similar condition, but if you’re having additional symptoms, you may suspect something else is going on.
This symptom along with chest pain and any other in this list should warn you to take immediate action and look for medical attention.
