What are the signs and symptoms of the condition?
Heart murmurs often have no symptoms and usually are noticed only during a physical exam. Symptoms may include:
rapid heartbeat, known as tachycardia
a pounding heartbeat, also known as palpitations
breathlessness, or shortness of breath
cyanosis, a paleness or bluish color in the skin
In severe cases, the heart murmur can be heard without a stethoscope.
