Heart Murmur Signs That Could Mean Something Serious

A heart murmur is what doctors call the rushing sound of blood through the heart. Though usually asymptomatic and largely harmless, murmurs are usually caused by some fault in the valves of the heart, which can cause leaking or inefficient blood flow. Alternately, a murmur could be the result of the heart beating more rapidly than normal, which causes an excess of blood to be handled by the muscle. Most individuals with murmurs may not even know they have one.
