|Heartbeat: Anatomy of the Heart|

- Structural abnormalities of the heart valves (most common)—these may be congenital (present from birth) or acquired later in life. Examples include:
- Abnormal holes or connections in the structure of the heart or vessels persisting after birth:
- Structural abnormality of the heart muscle:
- Other congenital heart conditions, such as:
- Endocarditis —infection of the inner lining of heart valves and chambers (endocardium)
- Cardiac myxoma—a benign soft tumor within the heart (rare)
- Age: 3-7 years old
- Rheumatic fever
- High blood pressure
- Autoimmune disease
- Congenital heart defects or disease
- Rapid breathing or trouble breathing
- Blue lips (cyanosis)
- Chest pain
- Palpitations (feeling of rapid or irregular heartbeat)
- Exercise intolerance
- Failure-to-thrive in children
When Should I Call My Doctor?
- Electrocardiogram (ECG)—This does not diagnose the cause of the murmur but can provide other useful information about the condition of the heart.
- Chest x-ray —to determine the approximate size and shape of the heart, and the presence of associated lung swelling (pulmonary edema).
- Echocardiogram —to examine the size, shape, and motion of the heart.
- Cardiac catheterization —to detect problems with the heart's structure, function, and blood supply.
- Blood tests—To check for evidence of a recurrent heart attack or other diseases that may affect the heart (such as kidney disease, infections, autoimmune conditions).
- Diuretics, angiotensin-converting enzyme inhibitors, digitalis—to treat heart failure
- Antibiotics—to prevent or treat endocarditis
- Replacement of defective heart valves with artificial ones
- Correction of congenital heart defects
- Removal of heart tumors
- Get prompt testing and treatment for strep throat to prevent rheumatic fever.
- Reduce your risk of atherosclerosis to help prevent valvular heart disease in the distant future. To do this:
