Can dizziness be a sign of heart disease?

Dizziness may be your body’s way of signaling heart disease. Your heart’s job is to pump blood throughout the body, including distributing oxygen to brain. A weak heart, however, can’t pump sufficient blood to brain, and without enough oxygen, you may suddenly feel dizzy or light-headed.

How can you tell if your dizziness is a sign of a heart problem? If, in addition to dizziness, you also experience nausea, sweating, shortness of breath, or pain in your jaw or neck, it may be a heart attack alert and you should seek immediate medical attention.
