Four rare symptoms of a heart attack include arm pain, jaw or throat pain, indigestion or lightheadedness, reports the American Heart Association. Heart disease is the number one killer for adults living in the United States.
Most uncommon heart attack symptoms are present in women's heart attacks. While most women think of heart attacks as occurring with chest pain, many women experience other symptoms and do not experience chest pain at all, according to ABC News. In fact, many women die at home from heart attacks because they do not pay attention to symptoms that do not involve chest pain.
