About Dizziness
Dizziness is a term often used by patients to describe symptoms ranging from light-headedness to feeling off balance, or to feeling a spinning sensation, like vertigo. Cardiologists consider dizziness to more likely be a heart symptom when it is closer to the sensation of light-headedness, which is the sensation of feeling like you may faint or lose consciousness. Dizziness that comes from a heart or vascular (blood vessel) problem is generally caused by the blood pressure being too low, either because of an abnormal heart rhythm, the heart not pumping enough blood, or from the blood vessels not working properly. Evaluation of dizziness often includes some type of ambulatory electrocardiographic monitoring, as well as taking pictures of the heart, so-called echocardiography.
