A heart murmur is a sound produced in the heart by the turbulent flow of blood. Due to the large size of the horse’s heart, this turbulence can be normal (physiological or flow murmurs) e.g. from a fast flowing large volume of blood, or from a high blood flow rate during exercise or in cases of anaemia. Murmurs also result from abnormal blood flow through the heart e.g. back flow through a leaking valve or flow through a hole in the heart.
