Well that depends on the cause of the heart murmurs. An ultrasound of the heart is usually the next step. Murmurs can be completely normal in some people. It could also indicate a leaky or misfunctioning heart valve, a small hole between chambers of the heart, or a dilated aorta or pulmonary artery. If a cause is found, then you can find out what treatments are available. But the cause needs to be identified first. Chest X-rays and EKG s are often ordered, but an ultrasound (or echocardiogram) will be the test that definitively tells you the cause.
