does mitral valve prolapse cause high heart rate?

Signs, Symptoms, and Complications They don't have any symptoms or major mitral valve backflow. When MVP does cause signs and symptoms, they may include: Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast)

Unlike angina, chest pain with mitral valve prolapse rarely occurs during or after exercise, and may not respond to nitroglycerin. Anxiety, panic attacks, and depression may be associated with mitral valve prolapse. Like fatigue, these symptoms are believed to be related to imbalances of the autonomic nervous system.

Mitral valve prolapse is a type of myxomatous valve disease. The tissue of the mitral valve leaflets and chordae are abnormally stretchy, so that as the heart beats, the mitral valve bows or flops back into the left atrium.

This family shows a close correlation between mitral valve prolapse and potentially lethal bradycardia. Excessive vagal tone is believed to be responsible for both bradycardia and sinus arrest, which in two patients was prevented by permanent demand pacing.

Symptoms. Although mitral valve prolapse is usually a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart condition. When signs and symptoms do occur, it may be because blood is leaking backward through the valve.

But in some people with mitral valve prolapse, one or both of the mitral valve leaflets have extra tissue or stretch more than normal, which causes them to bulge like a parachute into the left atrium each time the heart contracts. The bulging may keep the valve from closing tightly.

Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse is also seen with some connective tissue disorders such as Marfan syndrome and other rare genetic disorders. It is also sometimes seen in isolation in people who are otherwise normal.

The mitral valve prolapse (MVP) syndrome has a strong hereditary tendency, although the exact cause is unknown. Affected family members are often tall, thin, with long arms and fingers, and straight backs. Mitral valve prolapse is more common in women from 20 to 40 years old; however, also occurs in men.

Mitral valve prolapse and regurgitation Sometimes mitral valve prolapse causes blood to leak back into the atrium from the ventricle, which is called mitral valve regurgitation. Congenital mitral valve anomalies are defects present at birth (congenital) that affect the heart's mitral valve.

They may be bothersome, but aren't usually life-threatening. People with severe mitral valve regurgitation or severe deformity of their mitral valve are most at risk of having rhythm problems, which can affect blood flow through the heart. Heart valve infection (endocarditis).

In some people, it does not cause any symptoms at all. However, mitral valve prolapse may get worse over time. When it does, it can increase the risk of serious heart problems, including infections, life-threatening arrhythmia, and congestive heart failure.

Like fatigue, these symptoms are believed to be related to imbalances of the autonomic nervous system. Migraine headaches have been occasionally linked to mitral valve prolapse. The migraines are probably related to abnormal nervous system control of the tension in the blood vessels in the brain.

Anginal-type mitral valve prolapse pain has a tendency to be dull. It may feel like pressure, squeezing, or heaviness in the chest (a crushing sensation), occurring and intensifying with activity and stress. The discomfort may also be felt in the back, the shoulders, and the arms, as well as the neck and the jaw.

Mitral valve prolapse is a common disorder but progressive mitral regurgitation usually occurs late in life and in only a few patients. Other complications such as bacterial endocarditis, stroke, and sudden death are far less common but can occur at younger ages.

Is mitral valve prolapse dangerous? In most cases, it's harmless. Most people who have the condition are unaware of it and their health isn't affected. However, in some cases treatment is required.

Mitral valve prolapse is a common cause of mitral regurgitation. That's a condition in which some blood flows backward through the mitral valve with each heartbeat. Over years, moderate or severe mitral regurgitation can cause weakness of the heart muscle, known as congestive heart failure.
