3. Dizziness
For some it is quite normal to feel dizzy when standing up rapidly, traveling by car or looking down from great heights. However, when an individual experiences frequent spells of dizziness and for no apparent reason, it may be a symptom of cardiovascular disease.
Occasionally, and for a variety of reasons, the heart may not be able to adequately pump enough blood to the rest of the body, including the brain which may result in dizziness. Having an abnormally slow heartbeat, known as Bradycardia, causes dizziness. Hypotension, also known as low blood pressure, causes dizziness. Arteriosclerosis causes a narrowing of the arteries which reduces blood supply to the brain and heart. Some patients experience severe dizziness right before a heart attack.
